Secondary glazing is a second custom-made window, attached to the inside of your existing window, creating a double glazed effect, with out damaging or changing your original windows. Clearview secondary glazing is designed to be discreet and compliment the appearance, décor style and property type. See our Quick Guide

Clearview systems are designed for internal applications and not designed to work on external applications where exposed to the elements.

The units are manufactured from a combination of a slim seasoned timber perimeter sub-frame pre-attached to extruded powder coated aluminium profiles, these contain the glass sections, to which numerous options are available. The standard glass is 4mm toughened other glass options are available on request.. All materials are from managed, recyclable, sustainable from abundant sources. See Our Product Guides

Fully Assembled, Pre-glazed Systems :

Our systems are easy install, in most cases supplied fully assembled, pre-glazed and installation ready. We provide comprehensive step-by-step measuring and installation guidance and precise frame profile details all accessible via the Help Centre.

Units will be supplied in a flat-pack form if both dimensions are over 1800mm or you can specify this during the quotation process in the extras area. this option does carry a surcharge.

The Four Critical Factors

With every project there are always 4 consistent categories that require consideration, the following is designed to assist you through this process…

Appearance / Performance / Practicality / Price.

APPEARANCE:

The system should blend with the existing window to ensure it does not look unsightly or out of place. Slimline sound tempting, but unobtrusive is the key! Lightweight narrow gauge profiles distort and promptly fail, causing operational and performance problems. Our systems are unobtrusive, high performing and long lasting. What do they look like [click here]?

PERFORMANCE:

Soundproofing: for best result maximise the air-gap as much as possible between the existing glass and new secondary glass, that will do most of the work, applying a thicker glass will help, this can be subject to personal preferences and budget. In the right conditions as much as 80% of the sound can be reduced, 5 times better than double or triple glazing. Recommended Read “What’s Best for Soundproofing”

Thermal-Insulation: The standard systems can increase the thermal insulation of the windows by as much as 65% this can be further enhanced using Low-E glass. Whilst it cannot guarantee a total cure for condensation it can dramatically reduce its presence and manage it far more effectively.

Performances can vary from property to property due to some of the unique circumstances of individuals and their building.

Clearview Secondary Glazing is also a great property security enhancement.

PRACTICALITY:

This does not always feature at the outset, but it is important to consider how easy is it to live with the system once installed, Ventilation, cleaning, maintenance and escape aspects. Heights, widths and weights should be factored to ensure it is not a major problem in the future or causes frustration. Choosing an opening system would always be advisable. Looking through the Product Range [click here]  will help or Viewing some of our Videos [click here].

PRICE:

Clearly Price is important to ensure you get the best value for money, considering items 1,2,3 will help you to achieve this. Cheaper options may be tempting, but a long term return on investment giving the total solution to your window problem is the key.

Just enter the tolerance adjusted width & height sizes, select the unit type and bingo there is your price.

• If Face or Reveal fixing in the reveal / recess: Use the tolerance reduced sizes you have taken using the Measuring Guidance 
• e.g. if your window measured 1230mm x 1520mm at the narrowest points in the recess, you deducted the recommended 10mm, you would enter / order the unit size 1220mm x 1510mm. this will ensure the unit is at least 5mm small on each of the for sides so it will fit and have some adjustability (the gaps are sealed and hidden by the trimming process).
• If Face fixing around the window – surface mounted to the internal wall, the unit needs to be bigger than the reveal / recess so add on the frame size to each side – frame sizes detailed in the Product Brochures 
• We do not make any adjustments or assumptions on the sizes you enter on the system, the details entered are taken as the build sizes of the units you require to fit. There is a +/- 3mm manufacturing variable to the confirmed sizes.

Clearview secondary glazing is a bespoke product tailor made to the customer’s specific needs, each unit is built to meet the most effective solution for Appearance, Performance, Practicality and Price. As there are many options available so there isn’t a simple off the shelf price. As specialists in this field our Help Centre is a great place to start.

The Standard Sub-Frame option is default set on initial product selection, applying the slimmest timber sub-frame to suit the aluminium frame profile:

Examples:

• Lift-Out & SL Hinge Units – 25 x 16mm
• Horizontal & Standard Vertical Sliders – 43 x 16mm
• Tilt-in Vertical Sliders & HD Hinge Units – 50 x 16mm
• The first number refers to the Front to Back depth of the frame, the second number is the Width of the timber facing you.

The XL timber sub-frame (Extra Long) can be applied as a preference or as required, extending the sub-frame to assist with:

1. Enables a pre-drilled reveal fix hole to be applied through the timber, behind the aluminium track rather than self-drilled through the track on site by the customer/ fitter, giving a simpler, cleaner finish.
2. It extends the frame slightly away from the primary frame to help accommodate protruding items, such as, handles, catches, staff beads etc.
3. Enables different systems to be coupled together, stack or form Bay Window structures, giving a consistent frame depth.
4. It will slightly increase the glass to glass air-gap when face fixing.

The XL frame is available on the following units:

• Lift-Outs & Hinged Unit SL: 43 x 16mm / 62 x 16mm
• Horizontal & Standard Vertical Sliders – 62 x 16mm / 70 x 16
• Tilt-in Vertical Sliders, HD Hinged & Double Hinged Units 70 x 16mm

The Outer Fixed frame remain consistent to the specification selected irrespective of glass thickness.

The Ultra profile: This refers only to the glazing panel supplied with the units, the outer frame remains the same.

• If a Standard Frame or XL is selected and the glass selected is to a maximum 6.8mm glass, the standard glazing panel is applied.
• If an 8.8mm or 10.8mm glass is selected the glazing panel only will default set to the Ultra Profile, this is a slightly larger section by approx. 2mm. The outer frame remains the same as the standard / XL versions.
• Why is this relevant? if a the same section was applied to cover all sizes, the thinner glass options would not sit snugly in the section.

Fixing Options general interpretations 

Face & Reveal Fixing is simply the direction the screw holes are placed, face fix: front to back, Reveal Fix through the sides.

• Face Fixing: this is the default set option – Front to back fixing, the unit is fitted in the reveal screw fixed directly onto the face of the primary window frame – tolerance deduction are recommended to ensure the unit will comfortably fit into the reveal / aperture.
• Surface Mounting: this is the same as face fixing – but the unit will be measured and screw fixed to the internal room wall around the reveal, therefore the unit will need to be bigger than the reveal – see product brochures for frame sizes. (this is a less common option, needed if there is no reveal or there are obstacles in the reveal, opening inward windows etc)
• Reveal Fixing: this is where the unit is placed in the reveal, side fixing, into the left right, top & sill of the reveal. This is applied to increase the distance from the primary window to the back of the unit, increasing soundproofing performance of accommodating protruding handles or catches etc, or if there is insufficient frame available to face fix into.  Measurements should be taken where the unit will be placed in the reveal and the same tolerance deduction process applied to ensure fit. . You can select a self drill option through the track as the most cost effect or select an XL (Extra Long) sub-frame and this will be pre-drilled for you. The options can be applied in the modify area of the FastQuote.
• Hole drilling arrangements:
  • Standard Sub-frame– default frames, namely: 25 x 16 / 43 x 16 / 50 x 16.

• • Face Fix: Pre-drilled in factory
  • Reveal Fix: self-drilled on site by customer.

• XL (Extra-long) Sub-Frame – namely 43 x 16mm / 62 x 16mm / 70 x 16mm.
  • Face and Reveal fix Pre-drilled in factory.
• Special Timbers: namely Bevelled, for splayed reveals or Bays, extra wide e.g. 43 x 50mm – self drilled by customer.

The Ultra profile: This refers to the glazing panel only not the outer frame supplied with the units.

• The outer frame remains constant to that selected e.g. Standard Frame or XL Frame applicable to the unit type.
• From the default 4mm glass to 6.8mm thickness, the standard panel is applied.
• If an 8.8mm or 10.8mm glass is selected the glazing panel will default set to the Ultra Profile, this is a slightly larger section by approx. 2mm, but sits in the same outer frame section of the thinner glass options.
• Why is this relevant? if the same size profile was applied to cover all sizes, the thinner glass options would not sit snugly in the section.

Yes, we can provide most glass types, based on the specific needs of your project.

The standard glass is 4mm toughened, This safety glass is a minimum requirement where building regulations demand health and safety considerations, including the distance from floor and doors.

All our glass options conform to BS6206: 1981 / BS EN 12600 for impact resistance. 

We do not offer float (non-safety glass).

Subject to panel size this may default to 6mm toughened.

Laminated, Acoustic, Thermal Low-E, and Obscure glass options can be accommodated.

The standard for Sliding, Lift-Out, Hinged & Insert panels are single glazed.

This ensure the frame profiles are manageable size to operate as an unobtrusive secondary window, creating a double glazed arrangement with the primary window. This offers significantly higher soundproofing performance than double glazing (which is a poor acoustic barrier) thermally it will offer equivalent performance to many double glazed products – see the performance data in the Help Centre 

• The Vision range can accommodate up to a 6.8mm glass
• The Vision Ultra Panel fits the standard frame options but can accommodate between an 8.8mm to a 10.8mm glass.
• The Vision HD Hinged System can accommodate up to a 28mm Sealed double glazed unit.

See our Full Glass Ranges options 

What is Low-E Glass?

Low-emissivity glass (or low-e glass as it is commonly referred to) is a type of energy-efficient glass designed to prevent heat escaping through your windows to the cold outdoors. Low-e glass such as Pilkington K Glass™ Range has an invisible coating which  reduces heat transfer and reflects interior heat back into your room. This can offer a 5-10% increase to the thermal performance of a non-coated glass.

With secondary glazing it is a hard coat application, it has a robust quality, but can be scratched if abrasive materials are used to clean the glass, see maintenance.

What is Laminated Glass & Acoustic Laminate Glass.

Both are basically the same structure, with 2-layers of glass sandwiching a polymer sheet, the plastic film us usually 0.4mm or 0.8mm thick, so a 6.4mm Laminate is 2 layers of 3mm glass either side of a 0.4mm film, an 8.8mm laminate is 2-layers of 4mm glass either side of an 0.8mm film.

With a standard laminate, the plastic layer will increase impact resistance and a high performing safety / security option.

With the Acoustic Options, it is exactly the same make-up, but the polymer liner is a material called Polyvinyl butyral (PVB) which enhances the ability to absorb and dissipate the sound energy within the glass structure more effectively.

Obscure glass options are avialble but priced on application.

It is difficult to give exact details, as every property and everybody can be affected differently by noise pollution, however the science confirms, Clearview Secondary Glazing can reduce noise by as much as 80% or by over 50 decibels, (a reduction of 3dB is equivalent to halving the noise energy) this is 5 times greater than either double or triple glazing. This is subject to final specification and installation limitations, these details can be clarified during a consultation with one of our advisors. But the number one target is to try and put as much space between the existing glass and new secondary glass, The bigger the air-gap the better the performance. if the space allows try and get 100mm + to an optimum 150mm to 200mm. where space is limited a thicker glass will help. We always recommend starting with a 6mm glass for soundproofing.

Soundproofing [click Here] for comprehensive information

Watch Our Performance Video

Predicting the levels of soundproofing you will achieve is extremely difficult due to the many variables concerning you and your property, however following these basic principles will ensure you maximise the potential for the best results.

In order of importance: –

1. The Airgap
   • This is the gap glass to glass
   • The wider the gap the better
   • Use whatever space is available to an optimum of 200mm+
2. The Glass
   • The thicker the glass the better the overall performance
   • The combination of glass and airgap will optimise performance.
3. Refining your choice
   • With a limited airgap consider an acoustic glass option to optimise performance
   • Where larger airgaps are possible acoustic glass will outperform a lower cost option however increases in performance are incrementally smaller.
4. Choice of System
   • Choose the system best suited to your primary window design and your needs for access.

More information can be found on our Acoustic Page [click here]

We have test certification which confirms that Clearview Secondary Glazing can enhance the thermal insulation of a single glazed window by as much as 65% or a U-Value of 1.868 W/m²K (a U-Value is the formula for measuring heat loss the bigger the number the more inefficient the window is, a standard single glazed window has a recognised U-Value of approx. 5.8 W/m²K. This performance is better than a Class C, with some products  this performance can be as much as A+. English Heritage and Historic Scotland carried out research through Glasgow University which showed secondary glazing out performed  double glazed replacement windows. This is subject to final specification and installation limitations these, details can be clarified during a consultation with one of our advisers. see our Thermal Insulation pages

Clearview Secondary Glazing has a proven track record to eliminate or significantly reduce condensation problems to a point where it is no longer a concern. The naturally occurring problem of condensation varies from window to window and property to property and whilst we can’t guarantee a total cure, the fitting of the Secondary Glazing creates a manageable chamber, reducing most of the problem and, where moisture absorption products can be placed, which are then 10 time more effective. see more details on our Condensation pages

The outcome of condensation is genuinely unique to each specific window and can vary in the degree of the problem even with windows in the same room. It is extremely common for windows to have differing levels of condensation after the installation of secondary glazing. It remains a trial-and-error process to try and manage the problem for each window. Some windows see an instant improvement and even a complete cure while other take longer to acclimatise and dry out sometimes never being completely cured.

The problem is wherever the is air, there is moisture, wherever there is moisture and surface to air temperature differentials change sufficiently, it is impossible to stop the dewpoint and the moisture condensing on the cold surface. Sometimes over sealing the window can contribute to the problem by creating a sealed chamber where the moisture cannot escape thereby a recuring problem of evaporation and condensation.

Secondary glazing cannot stop condensation where the temperature differential occurs, but it can far more effectively manage the problem.

1. It will help to reduce the moisture content in the chamber between the internal and external glass
2. It will create a more stable equilibrium of air temperature reducing the chance of the dewpoint being reached.
3. The introduction of silica bags will soak up residual or recurring moisture, we would suggest 150g to 250g bag sizes, the larger the window the bigger the bag.
4. Newley installed systems – the fabric of the building will have been exposed to moister for a considerable period, so there will be a drying out period where moisture will be evaporating into the chamber, sealants and fillers extra will contribute to this. This can take weeks, even months and is subject to the time of year.
5. We are aware of an increased issue and notification of condensation not with the systems but with increased customer enquiries concerning the problem in their properties. This appears to be the exceptionally wet weather combined with temperature fluctuations and peoples energy /heating management. The high degree of moisture and fluctuations in temperatures is increasing the appearance of the problem.

The best and quickest solution we can advise and recommend is the introduction of silica bags into the chamber, this accelerates the drying, soaks up residual moisture and can keep the environment dryer for longer periods of time than if they are outside the chamber being exposed to higher moisture levels. Silica bags of varying sizes can be purchased from the likes of Amazon or E-Bay.

Obviously, there is the temptation is to keep opening the secondary glazing to “mop” up this moisture, but all this does is start the process over again. Thus, becoming a never-ending cycle. We recommend leaving the silica packs in the cavity and resisting the temptation to open the secondary. In our experience the moisture will reduce as things balance out, but if the units are regularly opened, the issue is unlikely to improve.

Additional suggestions to improve the control of condensation in the home:

1. Increase the running time of kitchen or other ventilation fans.
2. Encourage moisture to escape by opening fireplace dampers or vents.
3. Open doors and external windows for a few minutes each day to air your house.
4. Air kitchen, laundry, and bathrooms during or just following use, closing any doors which allow steam to permeate the rest of the house.

Panel movement in the units is to be expected and if the panels are sealing and interlocking when closed, the seal integrity will be intact.

We are predominately an internet based business, where all product details and information can be accessed online via the Help Centre

Our Cedar House, Sheffield address, is our formal registered office and not customer facing, if you are wanting more specific information, we recommend you initially email us at [email protected] or use the Contact Us option to advise on any details required.

Products can be viewed at the Factory near Rotherham in South Yorkshire , as a working factory this is on a strict appointment basis only, ensuring your visit can be fully accommodated.

For Supply Only: No, we do not visit site all details need to be managed by the customer or their selected tradesman. All support information about the process can be accessed via the Help Centre [click here] 

Supply & Installation service: If you fit in our Installation Area [click here] we do not arrange speculative site assessment visits, the process requires an initial information gathering, whereby the customer send photos and rough sizes of their windows, we assess these and offer proposals and price estimates. If the project moves forward a formal site survey is carried out for unit manufacturing purposes.

The Measuring Process is easier than you may think, whilst very important it does not require pinpoint accuracy.

The idea is to ensure when fitting into a reveal or within a frame boarder, the unit is slightly smaller than the tightest narrowest points. this ensure the unit will fit and gives some room for adjustment, we recommend a 10mm tolerance deduction to the total measured width and height, this is the build size of the frame and the sizes used to get a quote.  Gaps and distortions around the frame are all hidden and sealed by the Edging Trim. 

See The Measuring Guidance

If you are surface mounting around a window reveal to the internal wall or around a glass panel (face fixing) – you will need to ensure the frame is wider than the recess to get a fixing into the frame/face of the area being treated, this would be adding the width of the frame on each of the four sides of the window – unit frame size details can be accessed in the Product Brochures [click here]

If your windows are too large for a single sized unit, you can couple units together either side-by-side or stacked one-on-the other. This can be done timber-to-timber or using a coupling bar, this replaces the sub-frame where the units connect. These can be added in the modify area of the FastQuote – “Add Extras.”

If you are stacking horizontal sliders which are wider than 1200mm wide, you will need to apply 70 x 16mm XL sub-frames and box support bars for each interlocking panel section, to support the weight and prevent sagging.

No, we can only offer this service with our installation option. Following our measuring guidance is easier than you may think.

Virtually all Clearview Secondary Glazing is easy access, and we always recommend considering how to best mange your windows should you install secondary glazing. The idea of taking units out in the summer and replacing in the winter rarely effective and generally causes frustration. Our systems are designed to be in-situ all year round and can simply hinged or slide open for quick and easy access for ventilation or cleaning at any time. Lift-Out semi fixed systems are available and offer a cost-effective solution for seldom accessed windows.

Horizontal Sliders, panels sliding left and right (all panels will slide), the panels can also be lifted out of the frame. Panels can be equally split across the width of the frame or offset to match the existing glass sections if required. With a 2 pane slider, both panels will slide. LH = Left Hand, RH = Right Hand, i.e. If the side you are likely to open most often (from inside looking out). is the Left side. the LH version should be selected, this means the Left Hand panel will slide in front of the Right Hand Panel, the Right sliding behind the left.

With a 3 panel standard slider (SS3) this enables the left and right sides to individually slide  in front of the centre panel, there will always be a pane of glass covering the centre, panels can be lifted out. If access to the centre panel of the primary window is required, a CO3 unit should be selected (Centre Opener). LH or RH versions an LH version means the panel will slide from the Left over the right.

Vertical Sliders, Panels sliding up and down, both panels slide, the standard configuration is the bottom panel will slide up in front of the top panel, this can be switch on request. Panels can be equally split of offset to match the primary window if required. Panels cannot be removed, but on some systems can be tilted out of the frame for easy cleaning. The panels are supported by hidden springs so will be held at a desired open position. The panels will not fully slide to the centre point some access limitations are to be expected. Magnetic window cleaning devices can be used to assist with cleaning access.

Secondary windows, or glazing, offer all the benefits to double glazing- improved heat retention, lower heating costs, lower greenhouse emissions, improved noise reduction and improved property security, as well as significantly reducing draughts and condensation. It is a lower cost option to full window replacement, and there if no disposal to landfill, it’s quick and easy to install and generally does not require any post-installation decoration. Most importantly, secondary glazing gives an improved living environment. In addition may existing windows have lasted 100 years or more, with little maintenance can last, for many more, protecting the character, charm  and heritage of a property for future generations to appreciate. They will outlast many replacement options without any disposal to landfill and with the enhanced performance they offer a very environmentally responsible solution.

Vision Vertical Sliders

Up Down sliding direction:

• A Sash style window system with spring balances replication a traditional weighted sash window.
• Twin Track, timber and aluminium profile.
• Glazing panel orientation  – default set to bottom panel on front track closest to the room sliding up in front of the top panel, top panel slides down behind the bottom panel.
• Available in 3 product options.
  • Standard Sliding: BVS – Both Panels will slide up & down to a set travel limit based on panel size and weight. There will be some access limitations, magnetic window cleaning devices can be used to assist with cleaning access. As an optional Extra at the point of specifying the unit build details, the glazing panel orientation can be switched to top, so the top panel slides down in front of the bottom panel – The orientation defaults to top with arched units.
  • Glide: BVSG – Panels can slide past each other – extra cleaning access. (cannot be arched or top oriented). The slide travel limit will be the same as the standard BVS, but the panels can be manipulated past each other, giving greater cleaning access to the back of the glass.
  • Tilt-in: TBVS – panels will slide and also tilt for for easy clean access. Subject to the size of the panels, the tilt is approx. 40o, small panels will have less of as tilt angle, with panels under 400mm the tilt arms cannot be fitted, but can tilt without support, manual support of the panel would be required.
• With all models the panels will not slide fully to the mid point, there can be an approx. 60mm-150mm offset at the overlap point when the panels are fully opened. This is subject to width x height by weight.
• Maximum single panel height 1800mm
• Panels cannot be removed.
• Panel sizes can be specified to the match the primary windows design, equally spaced or offset with larger and smaller sections.

Fully Assembled, Pre-glazed Systems :

Our Vertical Slider systems are easy install, supplied fully assembled, pre-glazed and installation ready. We provide comprehensive step-by-step measuring and installation guidance and precise frame profile details all accessible via the Help Centre.

Note: When onsite reveal fix DIY track drilling, you cannot (do not) drill the top left/right side sections of the frame, this can cause damage to the spiral springs contained in the tubes. Drill where possible to the lower frame section. See the full Installation Guide. Fixing materials are not included – e.g. screw or packing materials

Vision Vertical Slider Glide

Up Down sliding direction: sash replica

The Glide system has been designed to give the panels a greater degree of slide travel, so the sashes can pass each other giving a greater degree of openability and access to the back of the glass for cleaning.

The top panel positioned on the back track, set back from the room, has no front facing grab fin. The operational process is as follows:

• The bottom panel has a  finger grab fin feature to lift up the bottom panel for standard day-today use.
• To lower the top panel, first raise the bottom panel to its fullest extent. Reach in and under to access the finger grab fin on the bottom profile of the upper panel. You can then either: –
  • Lower both sashes down to access the primary top sash.
  • With a little force and whilst supporting the lower panel, pull the top panel down and past the interlock point. There is a degree of friction here an particularly with newer units, this can appear to not want to pass, but it will.
  • Simply reverse the process to return the unit to its closed position.
• Not ideal on windows where the panels are notably offset e.g. 70/30 split top and bottom panel, as accessing the internal top panel grab fin may be difficult to reach.

Vision Insert Panels 

• The most basic of secondary glazing systems, an aluminium frame 17mm x 19mm surround a piece of glass.
• Drilled on site, 7mm from the external edge of the frame. Front-to-back Face Fixing only ( 3mm screw – suggested length 40mm subject to panel weight, notably heavy panels may require a longer screw length, screws not supplied)
• Measuring:
  • If Fitting into a recess, we recommend applying the standard 10mm tolerance deduction for the panel build size, ensuring the widest part of the panel will fit into the narrowest part of the recess. – e.g. if the recess was 900mm x 1000mm the panel build would be 890mm x 990mm.
  •  If surface mounting around a piece of glass – ensure the measurements taken are approx. 25mm wider than the glass area, giving sufficient face to screw fix into.  e.g. if the glazed area being covered was 900mm x 1000mm the build size would be 925mm x 1025mm
• Semi-permanent installation requiring unscrewing fixings to remove. 
• White powder coated aluminium as standard – other colors are available.
• There are size limitations for this product See Min/Max Guide
• With basic systems, expectations and performance can be less than the standard product range.  
  • See Our Insert information page [click here] 
  • See our Insert Product Guide [click here]
  • See the full range of Product Guides [click here]

Yes. In most cases, secondary glazing meets the requirements of Buildings and Conservation regulations associated with both Grade II & I listed buildings, as it is a completely reversible installation that does not effect the fabric of the building. However, subject to your property listing status, we recommend liaising with your local conservation officer who will be able to give you further advice.

See examples of our Listed Building project portfolio 

Primary windows are rarely square and parallel sided, so you need to ensure the widest part of the secondary unit (including the sub-frame) will fit into the narrowest part of the area it is being fitted. Any gaps around the frame are then covered and sealed with the edging trim supplied with the units. It is particularly important that the units are not too tight, and most problems occur because of this,  whilst some adjustments can be made to the Sub-Frame, if the unit is too tight it won;t fit and cant be used, if squeezed in it can distort and cause operational and performance problems. a small gap around the units ensures maneuverability and position to ensure the perfect fit.

See our measuring guide

The recommended 10mm tolerance deduction is for guidance only as the aperture/reveal distortion will dictate unit size/fit adjustments  and requirements.

No, we are unable to determine what fixings and packing requirements may be needed due to the vast range of differing window styles and materials. All  fixing material requirements screws, packers etc are detailed in the installation guide.

We do offer optional fixing kits, these can be added to your quotation at the point of creation or you can visit our online store

Trim: With white units the standard trim supplied free of charge, it is white 20mm wide uPVC, this is easy to work with, matches the colour of the unit and is maintenance free. 

With colour units a 20mm wide timber painted trim is supplied as standard to match the units.  this may  require painting and upkeep at some future point.

The trim supplied is in sufficient lengths to cover the front face only, sealing off gaps between the reveal wall and the frame. Additional trim for back trimming or side covering is available as an optional extra.

The customer must satisfy themselves that the standard trim supplied is sufficient for their needs.

Alternative sizes are available as an optional extra and can be added to the quote / order as required..

Please note, the trim is an industry standard product, if you find that an alternative trim is required after delivery, this can be purchased from local DIY merchants or a variety of online retailers. we are unable to supply trim as a standalone item.

It varies. It’s dictated by the size and complexity of the order. Based on a  window approximately sized 1000mm x 1200mm, installation should take under an hour. On an average order size of 8 windows, installation can be complete within a day, it is relatively simple for anyone with basic DIY skills . Clearview secondary glazing is pre-assembled, pre-glazed and pre-drilled for ease of installation. 

see our Installation Guide

We always recommend that the sub-frame is included, this is pre-attached to the system at the point of manufacture. This has several benefits and is hidden by the edging trim on completion. It enables gaps around the frame in out of square apertures to be easily covered and give a better blended and unobtrusive finish. It enables minor adjustment to be made on installation and to notch out around lumps, bumps or cables etc. it also enhances insulation performance with expansion and contraction during seasonal changes.

The sub-frame is a value engineered product, designed to be hidden from view on completion, it is designed to protect the unit in transit and can arrive marked, with nicks scratches, chips cracks and knots, joints in the sub-frame will move in transit. All these aspects are perfectly normal and will not deteriorate the performance or final appearance of the unit when fitted. 

Standard & XL (Extra Long) sub-frames are supplied primed, 

All options can be selected as face fix pre-drilled in the factory

Standard frame options can be reveal fixed, by self-drilling through the track onsite.

All XL frame option can be reveal fix pre-drilled in the factory.

Special timber sub-frames e.g. Bevelled will not be pre-drilled.

Click on image below to view optional extra sub-frame selections.

With bespoke cut timbers not all surfaces will be primed.

No Sub-frame:

Units can be supplied without the sub-frame, this is a special-order requirement and Clearview need to apply this on behalf of the client. Measuring becomes far more critical as onsite adjustments can’t be made and gap filling around the unit must be considered. The price can alter as the aluminium and square meter size of glass increases to replace the timber area, these material are more expensive than the wood.

See No Sub-Frame section Example [click here]

See our Quick Guide &  Installation Guide & Trimming Guide

Clearview frames are available in a wide range of colour options. Clearview Secondary Glazing systems are supplied in White as standard. However, there are a number of stock colour options, Cream, Dark Brown, Grey & Black, these carry an additional charge over the standard finish.  200 Bespoke colour options are also available, price on application. see our Colour Range details 

COLOUR SAMPLES:

We can send out stock colour samples, these are small aluminium profile sections from our Colour Option Range [click to view]

There is a £5.00 inc. VAT postage & packaging packing fee, which is refundable if an order proceeds,

We can send a total of 3-samples for the £5.00 and you can order via our Make-a-Payment page [click here]

Yes. In most cases Clearview can provide glazing units to fit most existing profiles, even complete circular designs, alternatively we can design a bespoke solution. if you send us some images we can offer advice, but in most arched cases we require a template for manufacturing.

View our Product Guides these show what shapes each system can accommodate

Skylight or Velux style windows, we also advise caution if trying to secondary glaze a window with a sloping or roof setting. it is critical to consider the safety and securing of both the frame and any moving/removable panels. Most sliding options do not perform well. We would advise a lift-out unit is probably best suited fitted with a locking bolt to secure the panel.

With regards to roof light and Velux style windows we must advise on the following.

Generally:

• The systems are not designed to be fitted in an inverted position, particularly with sliding systems where the gravitational weight is being applied to the wrong face of the unit which can affect functional operation.
• Opening / access to the primary window can be affected. If trying to fit a unit in the aperture of the Velux, the secondary frame is likely to prevent the Velux from pivoting open. It can be possible to surface mount a unit around the aperture so if the glass panel is moved the Velux can still swing through.
• There are health and safety considerations to be aware of in terms of frame and glass panel securing to ensure neither can fall or detach or subject to height, create a head impact protrusion . We therefore wish to ensure these aspects are not missed and understood from the start.

Options: subject to your consideration on the above outlines detail.

• Customers have purchased and installed our system to Velux or similar window styles and have reported a satisfactory outcome.
• We would suggest the most suitable system would be a Vision Lift-Out [click to view]
• Whilst optional, we would also recommend the inclusion of a screwdriver activated turn-locking button which will secure the panel when fitted and it can only be removed when the button is disengaged.

Locking Button

• Due to the pivoting design of a Velux system, the swinging in part of the window causes an operational limitation. If a unit is fitted inside the reveal (mouth of the aperture), if the glass panel of the secondary unit is removed. The Velux panel is likely to clash with the fixed part of the secondary frame, preventing it from fully opening. It may allow some venting, but not the full swing through for full cleaning access etc.
• The suggestion, and hence the slim-line unit would be to surface mount the units to the internal roof, around the aperture, so the frame would protrude off the ceiling by 25mm, but would clear the reveal allowing the Velux to swing through.
• More details on the products & services including instant prices can be accessed via the Help Centre [click here]

The Gasket is simply the rubber seal which holds and seal the glass into the glazing panel. available in white or black

White, cream or lighter colour units this would default set the a White Rubber.

For darker colour units this would be default set to Black Rubber.

If you have a preference you can override the default setting and pock black or white for your unit.

The visibility of the gasket is minimal with just a few millimetres showing between the glass and aluminium frame.

We do have specialist installation team and can provide a fully comprehensive Survey, Supply and Installation service, this is a highly qualified City & Guilds trained team covering all certification requirements for both domestic and commercial projects.

However, this service is limited by size and location of project, and generally limited to an approximate 50-mile radius of our Sheffield Head Office for most domestic sized properties. Initially, we request if photos of the windows and some very approximate sizes can be emailed to us, we can then evaluate and offer some price proposals and options to establish interest . We try to offer a financially attractive installation service, but, the greater the distance and smaller quantity of windows required, the less competitive our offer becomes and it may be more advantageous to consider our Supply Only service.

[Click here] to see if we can fit in your area and submit and enquiry.

Commercial work is evaluated on a project by project basis

Survey visits are only arranged following acceptance of one of our proposal options.

Where we are unable to offer an installation option, why not consider our Supply Only service for a DIY approach or using a local tradesman, this is easier than you may think and very cost effective.  see our Help Centre for more details.

Unfortunately we cannot recommend fitters, it is not possible to keep an up to date national database of installers where we know they are accepting work of this nature or their quality of customer service is appropriate. we prefer the customer to vet and verify their own installer.

The DIY approach can be easier than you may think, if you are not DIY confident, you may have friends, family or neighbours who are and could be called on for help.

If you are still struggling to find assistance, we can suggest using the Which Trusted Trader service, just enter your postcode and search for carpenter / joiners, this should give you a list of tradesman in your area who would be more than capable of carrying out the work. 

Other than drilling several small fixing holes into the existing window frame or surround, your primary window remains untouched and fully intact when you install Clearview secondary glazing. You will still be able to access your primary window all year and in most cases with a hassle free sliding or hinging option instant opening for ventilation cleaning and maintenance is assured.

Clearview systems are designed specifically for internal applications where they are not exposed to the elements.

If fitted externally, no claims can be accepted against warranties, guarantees or performance or any consequential aspects related to the installation.

No, unit or profile samples are not available, due to the range of profiles and section types, weight and bulk of the materials it is simply not practical to manage sample options or a department to facilitate this.

Full frame section details and profiles sizes can be accessed in the Product Brochures [click here]

You can order a small version of a system through the standard FastQuote service [click here] This would be on the same terms and arrangements as ordering a unit, but the price would be reflected in the smaller size.

COLOUR SAMPLES:

We can send out stock colour samples, these are small aluminium profile sections from our Colour Options Range [click to view]

There is a £5.00 inc. VAT postage & packaging packing fee, which is refundable if an order proceeds,

We can send a total of 3-samples for the £5.00 and you can order via our Make-a-Payment page [click here]

 In the Quote reference box, just type in “ColSam & the colours required” from the colour options range.

In the value box, type in £5.00. or the value for the quantity being ordered.

No – in most cases, unless your room is already undergoing decoration, the installation of Clearview Secondary Glazing does not require your room or area to be cleared or covered, other than allowing access to the window area. Your room will be left in a comparable condition to before the installation.

All units are subject to Minimum & Maximum Build Sizes which also includes:

• The Glass type appropriate for the unit:
• The total Width & Height of the unit type.
• The Glazing Panel Size & Weight in any of the sliding unit types.

If the quote will not calculate and no notification is shown confirming the problem, it is likely you are trying to create a specification that the system cannot calibrate and you will need to make adjustments to bring it back into a viable build specification.

Scenarios:

The Width x Height x Weight will therefore determine the production capability.

1. If the Width or Height is too large or small for the unit type being created you will get a notification to tell which which.
2. Units are default set to a 4mm glass thickness during the initial quote creation, if the unit size goes above a certain threshold, it will default to 6mm to ensure safety and stability, the thinner glass will cause flexing and other potential problems. 
3. Horizontal Sliders:
   • Unit heights over 1800mm will default to 6mm glass thickness minimum.
   • If any of the panels are over 1200mm wide they will default to 6mm glass minimum
4. Vertical Sliders:
   • The Maximum Height of each sliding Panel  is 1800mm within the maximum overall unit height of 3300mm – Subject to the overall Width x Height ratio this may default to 6mm glass for the panel sizes required.
   • Spiral Spring Balances – panel support mechanisms. these are sized and calibrated based on the size & weight of the panels.
   • If the unit is very small and below a certain threshold it will default to an 8mm glass, this is necessary, as the minimum available spring size over powers the weight of a thinner glass forcing the panels to open without control.
5. Lift-Outs and Hinged units:
   • 6mm glass will default apply for any units over 1800mm in height.

If the unit will not calculate, try a different glass of adjust any panel sizes, if not change then it is likely that unit specification is not viable,

• Glass Imperfections or blemishes: if the issue can be detected with normal vision from a distance of 2-meters, we will offer to collect any removable panels or complete units where panel removal is not possible, for rectification and return.
• Smashed or cracked Glass: We only supply Toughened or Laminated Glass. Any faults within the glass structure will normally cause failure with minimal flexing or movement, therefore we expect that the manual handling of the glass from manufacture, unit conversion and distribution, will stress the glass to  the extent where any faults or flaws will become apparent before or by the point of delivery. Failure thereafter can only be considered as handling or interaction with circumstances outside its structural capability.

If you experience a problem with your order,

Expectations: 

When the units arrive, please inspect them to ensure they are correct for your application, if we do not hear back from you within a period of 10-days we will assume they have been accepted:

• The timber sub-frame can be damaged scratched, chipped, cracked split with blemishes and marked, this is normal, the sub-frame is designed to be chopped and notched on site to assist with the installation and is hidden when installation s complete. it also serves as additional transit protection to the aluminium frame.
• Custom Timber Sub-frames e.g. Bevelled or bays will not be pre-drilled.
• The frame can be out-of-of square as they are not a ridged structure until installed. The installation process will pull the unit back into square.
• Panel operating buttons may be tight as the units will have moved in transit, so manipulation the panel to free up may be required.
• The units can be a little dusty or conveyor marked, with small amounts of swarf  they are direct from the factory and it is standard practice that they will require a clean down following the installation process. So to improve efficiency and cost, the unit are cleaned to an expected level but based on the requirement of a final clean down on completion.
• Please refer to the Installation Guide for more details 
• Fully Assembled, Pre-glazed Systems :Our systems are easy install, in most cases supplied fully assembled, pre-glazed and installation ready. We provide comprehensive step-by-step measuring and installation guidance and precise frame profile details all accessible via the Help Centre. Some units will be supplied in a flat-pack form if both dimensions are over 1800mm or you can specify this during the quotation process in the extras area. this option does carry a surcharge.

Observations & Claims:

Please see our Returns & Rectification Policy

Please refer to our Terms & Conditions 

CLAIMS: In the first instance any claims should be submitted by email describing the issue to [email protected] and where possible include photos of the issue being described. Note: if the unit/s are transported to another geographical location from the original drop site, claims for damages will not be accepted, 

If you follow the recommendation and advice set out in our Help Centre Guides [click to view] this will minimise error. We want you to have the best service and outcome possible Contact Us if you would like to discuss this further.

IMPORTANT: Following a review of any documented details supplied, If the problem is clearly evident of a manufacturing fault or issues caused by prior handling, the unit/s can be collected for rectification, this will be arranged in as timely and as fair and reasonable time frame as possible  and subject to the issue concerned. However it is important to note that if the unit/s when inspected on their return, if no remedial action is required as the issue would have been corrected during installation using the guidance provided, charges will apply for return of the unit/s.

If a unit has been ordered in error by the customers oversight or specification inaccuracy, should a replacement unit be  purchased, we are unable to collect and dispose of the original.

Glass thickness can often be misconstrued by placing the thumb and forefinger to either side of the glass.

This can appear to show the fingers almost touching suggesting the glass is paper thin.

Understandably this can cause concern questioning if the glass is as ordered. This is simply an optical affect as demonstrated below.

Checking the glass panel/unit weight is the simplest way the check the thickness, if specialist equipment is not available or the calibration of calipers when measuring precise millimeters.

4mm Glass = 10kg m2 / 6mm Glass 15kg m2 / 8.8mm glass 22kg m2 / 10.8mm glass 27kg m2.

 Glass weight = 2.5kg x mm glass thickness  x unit m²

e.g. unit 950mm x 1200mm = 0.95 x 1.2 = 1.14 m² with 6mm glass. Calculation is 2.5 kg x 6mm = 15kg x 1.14 m² = 17.1 kg weight.

Optical Effect:
