Soundproofing

Enjoy enhanced acoustic insulation with Clearview secondary glazing.

Unwanted noise is a problem in many homes and commercial buildings, particularly in towns and cities and period properties with original single glazing. Traffic, street and aircraft noise adversely affect living and working environments, causing unwanted stress, a lack of concentration and worse.

Secondary glazing is the most effective solution for reducing intrusive noise through glazing. Secondary glazing reveal fix frame formats are attached to the side wall of the window reveal rather than to the face of the primary window, so the secondary unit can be positioned away from the primary window for optimum sound insulation. The wider the gap, the better the sound insulation – see the Acoustic Performance table. With the right specification of secondary glazing and acoustic glass, a reduction in excess of 50 decibels can be achieved, which can be 5 x times that of double or triple glazing (that’s a reduction of almost 80% of the noise entering a room). A reveal fix is the option to select when there isn’t sufficient frame on the primary window to attach the secondary glazing unit.

Secondary Glazing for Double Glazed windows?

Secondary glazing can also enhance the acoustic performance of double glazed units. If fitting secondary glazing to an existing double glazed window to enhance acoustic insulation, it is important to specify a different thickness of glass. This ensures the structure of the 3 panes is not uniform – this lack of uniformity improves sound wave dissipation. If you are unsure of the existing structure of a double glazed window, a 6mm or 6.4mm thickness of glass would be a good start point. 

No matter what the double-glazing salesman my tell you, double or triple  glazing is no match for secondary when it come to soundproofing, don’t spend a small fortune on replacing existing double glazing windows or glass with all the mess, hassle and landfill environmental impact. We get calls constantly from people who have done just that and are very disappointed by the results and are back seeking a real solution, which alas will be more expense which could have been avoided had they gone straight for the secondary option.

The cavity makes the difference

The gap between an existing primary window and the secondary unit makes a big difference to the level of noise insulation. Unlike sealed units, where the two pieces of glass are rigidly coupled together, the primary and secondary windows act as independent barriers to the transmission of noise. The greater the cavity between them, the better the dampening effect of the combined window. A minimum of 100mm+ gap is recommended, more if the space is available up to an optimum 200mm. This gap can offer more performance than the glass, so don’t be put off by an expensive acoustic glass, you can still get amazing performance with lower cost glass options.

Mind the Gap

It is the glass to glass airgap that really boosts the performance and is why secondary glazing is so much better for soundproofing than double of triple glazing, just use as much space as your window structure will allow. 200mm is the optimum, but not all windows have that, so try to position the unit to maximise the space available. Even where minimal space is available with the secondary and primary frames combined, you may find you have 100mm by default.

A wide choice of glass options

Clearview offer a wide choice of glass options, including a range specifically engineered for acoustic insulation to ensure optimum acoustic performance. Choose from Stadip Silence for a premium solution, or choose a 6mm glass and still achieve significant results. It’s worth remembering that the inner and outer glass should have different mass to avoid ‘sympathetic resonance’ which increases noise transmission at higher frequencies, and that thicker glass improves performance, particularly at lower frequencies. Acoustic laminate glass has a special interlayer that helps improve high frequency performance and is particularly suited to dealing with traffic, rail and aircraft noise.

Please note all performance data presented has been independently tested and certified confirming the levels of sound reduction our systems are capable of achieving, these levels can vary subject to specific apertures, locations, other influencing factors and untreated areas within the property they are installed.


The Basics

There are really only 2 principle steps to apply to ensure the optimum sound reduction performance for your specific window.

  1. Try to achieve the widest gap between the primary glass and secondary glass that your window structure will allow.
  2. Incorporate the thickest glass your budget will allow. 

Using different thicknesses of glass will always have a positive effect on reducing noise, so if you know the glass thickness in the primary window, always select a different thickness for the secondary.

Trying to predict the outcome in sound performance comparing one glass type to another is a tricky business, the above 2-step principle is a good a measure as possible, e.g.:

In laboratory tests:  using the optimum scenarios 

A 6mm glass can provide a circa 50dB sound reduction

A 10.8mm glass can provide a 55dB sound reduction

3dB is equivalent to halving the sound energy 

10dB would be considered what the average human ear would class as halving the noise level.

So, the difference potential from a standard enhanced 6mm glass to a high-end 10.8mm glass could be considered as a 50% enhancement in comparable performance. The difference in-between each thickness may only be 1 or 2 dB.

These factors may be more notable to some than others.

Key Benefits of Secondary Glazing

My second purchase from Clearview, 17 units in total and no complaints from me. As before all units were manufactured with precise accuracy with the same overall quality of the frames and glass. Delivered on time by a very helpful/friendly driver. Just the final finishing to complete but I can already feel the benefit with a reduction in road noise. No doubt that when winter arrives I will also have the benefit of better insulation. The service level of this company and their products are first class - recommended.

The secondary glazing has been installed for a couple of weeks now and it has made such an amazing difference to the heat retention in the room. You really can't see the secondary glazing; it matches the existing window so well. It looks good, it works, I'm spending much less in fuel to heat the room and for one person at least 2020 is not ending in tiers.

Just thought I'd write to you and tell you how pleased we are with the three windows we received from you. Put them in over the weekend, which was straightforward, and now we can hear the difference from the road outside. No longer car engines, just a hum or hiss. We were able to give a 5 inch airgap to the back of the exterior double-glazed windows, and the secondary frame and panes are not in the least obvious. We'll be ordering from you for the other two windows on the road side of the house very soon.

Best investment in my property so far! I live in a Grade II listed building, which was built in 1850, so double glazing is not permitted. I have single-pane sash windows which used to have a lot of condensation on them, rattled as the draughts came in and were useless against noise. Luckily, I discovered Clearview at the end of last year. The ordering and delivery were easy with excellent communication throughout. Since I fitted the units condensation has been eliminated, no more draughts and external noise has been greatly minimised. The windows are well made and easy to install. They’re so good I’ve yet to put the heating on this year

Can I say how pleased we all are with the secondary glazing at The Cottage, Badminton. The windows in the Library, Office and the lockable lift outs for the skylights look really good. Please thank Wez & Dan for me for all their hard work and in keeping the Cottage tidy whilst fitting. Many thanks to you as well for putting our minds at rest from the start of the project. The Cottage is now warm and toasty with new heating and wood stove installed in the library. What a transformation!!!

Clearview customer service is outstanding. This is an excellent product that can be installed by any competent DIY'er. My units are single pane hinged double glazing and fitted in a listed building. They are invisible when viewed from the outside and so unobtrusive on the inside.

From the start I was confident about this company. I had a non standard requirement and they spoke at length about it. Furthermore they arranged for a delayed and specific delivery to fit in with my availability. I was able to fit and trim the unit in 2.5 hours and for anyone with DIY skills it is easy enough. It has reduced noise considerably despite not being at the recommended distance from the existing window. It is also invisible! I have attached photos and it is difficult to see the additional unit! Highly recommended this company.

From start to finish, our dealings with Clearview Secondary Glazing could not have been better! They proved to be a thoroughly professional business, who carry out an all round first class service by not only providing and installing a superb product but also by explaining everything in non-ambiguous terms; keeping the customer informed at every stage; turning up when they say they will and for being, well, just very nice people! Worth every penny! Thank you very much Andrew and Craig (and those behind the scenes we didn't get to meet!)

I'm completely made up with my new Clearview Secondary Glazing windows. Not feeling confident with your DIY skills? Fear not, as from start to finish I felt totally supported by the team at Clearview SG. I had loads of questions about the process (measuring, ordering, installation etc) but no question was ever too much trouble for them. I made a few mistakes when measuring, but they check, double check and triple check before they begin manufacturing. The windows look great and work perfectly. I would recommend them to anyone. Thanks heaps to Andrew, Deborah and the rest of the team. Brilliant!

Clearview Secondary Glazing

I would like to take the opportunity of thanking all at Clearview for the supply of my secondary glazing units. We have an older style house with aluminium framed double glazed windows in hardwood surrounds and although they suit the property they are not as efficient as modern glazed windows. We didn't want to upgrade the windows as UPVC frames would look wrong. I had fitted some DIY Polycell units many years ago but decided that we would now like to do the job properly with toughened glass and the ability to open the centre panel only to get to the fanlight, these 3 panel sliding units really do the job. After a lot of online searching we chose Clearview and am so pleased we did, the service has been great, from the online quote to placing the final order, we have been kept in touch all of the way even to the delivery driver phoning to fix a delivery time. I have finished the installation and would have no difficulty in recommending both your product and your company. Many thanks David Terry.

I would just like to say what a fantastic product the Clearview secondary glazing has been in our bedroom, without going over board it has improved our quality of life literally overnight, we have spent a lot of years complaining about traffic and human noise from outside and the secondary glazing has pretty much solved the problem, not to mention the lack of condensation. Great solid product and helpful advice from your staff. Easy to fit from a lay mans point of view, I have decided to go with another 2 windows down the noisy side of the house, will be in touch.

We wanted to express our sincere thanks for making the whole process run so smoothly - from our initial contact with you, through to the actual installation of the units. Throughout the entire planning stage, you have been extremely helpful and courteous. And, in relation to the actual installation, we have absolutely nothing negative to say. They were polite, professional, worked hard to keep any disruption to a minimum, readily answered any questions we had (of which there were a few) and, to sum up, it was a pleasure having them in our home. By the time they were ready for leaving, they had done such a good job cleaning up after themselves, that the only thing to show for their visit was the fact that we now had our wonderful secondary glazing in place. And, on this note, we are absolutely thrilled! Other than the obvious benefits from the sound insulation, you wouldn't know the windows were there - they are so unobtrusive, it's incredible! It has made a huge difference in cutting down the noise from the traffic, and also noise (previously heard, but no longer) from people going past, or from youngsters playing out.

I'm quite surprised at the appearance of the finished article. It's fantastic. I stood here now, and I see can't hear anything at all, which is amazing. It's very peaceful, which is what we wanted. I can't wait to get good night's sleep tonight!

Our bedroom overlooks a railway line, so we were primarily looking for acoustic insulation (we’d had secondary glazing in our last home, so knew how effective it was). After some online research, we went with Clearview this time, as their prices are competitive, their online quotation system quick and easy, and – perhaps most importantly – their customer service responsive and helpful. As it happened, here were a couple of glitches (on my part) with measuring and specifying, which Andy at Clearview ironed out for me with no fuss. Once ordered, the product arrived on time, and has proved highly effective at reducing the noise. I actually enjoy watching trains go by in near-silence, and have since ordered a similar unit for our living room, to repeat the experience! I can thoroughly recommend secondary glazing in general, and Clearview in particular.

The lounge is much warmer since secondary glazing was fitted, and the condensation has stopped. We have also noticed a reduction in noise from the main road outside. We really like the fact that the secondary glazing does not detract from the look of the bay, inside or out. We don’t notice it.

We had secondary glazing fitted in January, and immediately noticed the benefits. Our dining room is much warmer, and quieter.

Fitting was a breeze – if you can handle a screwdriver, you can fit them yourself. Immediately noticeable was the reduction in traffic noise from the fairly busy road. The added bonus of the extra insulation they provide is noticeable too, but best of all, after 4 nights now, I have not had a single drop of condensation on the original double-glazed windows yet. Anyone considering buying these but having second thoughts or doubts? Don’t delay any longer. Not only is it a great product, but the sales staff were very patient and helpful with me at the start of the process.
