Condensation Solution

Help eliminate condensation in your home with high performance secondary glazing.

Thinking about secondary glazing to get rid of condensation in your property? Good decision. In most cases, fitting Clearview secondary glazing in your property eliminates condensation. Occasionally there are conditions where it can’t significantly reduce condensation, generally installing secondary glazing really helps.

Secondary glazing provides an effective internal seal, allowing for balanced ventilation in the space between the primary glass and the secondary glazed unit. This seal prevents the inner glass becoming too cold, stops condensation forming. Clearview secondary glazing is a simple to fit, cost-effective solution – whether you fit yourself, or have a Clearview approved installer fit for you.

What is Condensation?

Air is full of moisture. The warmer the air, the more moisture it can support. When air temperature drops (in Autumn, for instance) the air can’t contain all the moisture, so tiny drops of water appear. You see it when you breathe on a cold day, or when the bathroom mirror mists over when you shower. That’s condensation.

Condensation appears where there isn’t much air movement – in or behind wardrobes and cupboards. It often forms on north-facing walls, or near windows.

What Causes Condensation?

Every hour, as we breathe, each of us add nearly 60ml of water to the atmosphere. Heating appliances, like paraffin stoves, contribute a staggering volume of 10 pints of water for every 8 pints of fuel used, and the consumption of 1 cubic foot of gas discharges 1 cubic foot of water into the air. Cooking, and washing and drying laundry indoors also add to this reservoir of water.

The condition of primary windows can contribute too. If they are ill fitting, they allow too much cold air to circulate between the glasses, causing condensation. Glazing putty in poor condition allows rain underneath, getting drawn inside the windows by capillary action, increasing the humidity of the air within the cavity. Building construction faults can create a condensation problem. Masonry in poor condition, or primary windows with rotten frames.

Clearview technicians have researched the problem of condensation, and acted on advice from the Insulation Glazing Association and the Ministry of Public Building and Works.

Sometimes, condensation is attributed to fitting secondary glazing. But building experts agree that’s seldom the cause, secondary glazing cannot create condensation where it didn’t previously exist.

It’s clear that condensation is a complex problem. And although, in the vast majority of cases, installing secondary glazing eliminates or reduces it, there are occasional cases where it’s impossible to identify the source of excess humidity, or effect a cure, our contract draws attention to this.

In many properties, other causes of moisture are evident, on walls for example, where visible dampness climbs upwards from floor level indicating rain penetration, or rising damp because of a faulty damp proof course. Many older properties don’t have damp courses. As well as the primary condensation causes, there can be an associated secondary cause; in that as the initial moisture evaporates the resulting salt crystals become concentrated on or near walls. Most of these salts eventually appear as efflorescence causing no further trouble, but some (notably chlorides and nitrates) remain, and being hygroscopic, absorb moisture from the air.

Outside, vegetation, climbing plants and faulty gutters can be sources of moisture. The condition of brickwork pointing and sills, and the way window and door frames are fitted should be checked, as they can affect the success of secondary glazing from a condensation point of view.

Despite adequate heat, without sufficient ventilation a small amount of internal moisture can become excess humidity. The modern tendency to seal our homes against bad weather also prevents buildings from breathing. By concentrating on preventing moisture from coming in, we’ve also prevented interior moisture from escaping.

Ideally, a building’s humidity, heating and ventilation should be balanced. The balance will vary seasonally, but a bit of time experimenting with finding the correct levels is often rewarded with a good measure of success.

4 steps to reduce humidity in your home

  1. Control the source of humidity. Vent gas burners, clothes dryers etc. to the outside. Fit extractor fans, particularly in kitchen or bathroom. Make sure you have adequate vents and air bricks throughout the house.
  2. Provide ventilation. Outside air is usually dryer, so dilutes the humidity of inside air. In older houses, this often occurs automatically because of constant infiltration of outside air through ill-fitting windows and doors.
  3. Heating. Provide dry heat to counterbalance most of the moisture produced by modern living.
  4. Air passage. Ensure existing air bricks are unobstructed.

Key Benefits of Secondary Glazing

Secondary glazing is a fantastic way to reduce heat loss, but did you know it has other benefits too?

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!!!

I am writing to you thank you for your excellent service throughout my recent purchase. The advice offered and pre-delivery service was fantastic. It is refreshing dealing with professionals and I believe this company is an excellent example of how everyone should be going about business. The secondary glazing has made a significant difference and I am very happy with the price.

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.

Clearview Secondary Glazing

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.

The quality of the products was perfect and I will be using them again. I wish everybody had the same customer service as Clearview. Overall, it was excellent.

Bought 2 units for our front bedrooms as we are on a noisy main road. Installed them yesterday and the difference in noise is amazing. I went for the 6.4mm laminated glass and positioned the units on the front of the window sill to give maximum gap.

Just to let you know we received the windows in good condition and have already installed them and are very pleased with the result. Thank you for all your help. We might be back for one more in the future. Many thanks.

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.

Just wanted to say we're very happy with the window. I'd also like to say how good the installers were, generally but also in terms of putting down dust sheets and cleaning up afterwards.

Thank you for all your help. We are very pleased with everything - all windows look so good, and standard of workmanship and tidiness of fitters was excellent.

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 secondary glazing has improved the insulation of our house. It’s much more comfortable. I can now work close to the windows without the discomfort of draughts. As a surveyor, I can tell you that Clearview’s work is high quality.

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.

Clearview Secondary Glazing

We had secondary glazing fitted in January, and immediately noticed the benefits. Our dining room is much warmer, and quieter. But, the most welcome change is that condensation no longer drips from the bay window. Clearview were great to deal with, we will be calling them again to look at the other windows in our house.

I had windows fitted and the difference they make to noise reduction is amazing, I was beginning to believe last night that cars had suddenly stopped using the road but when I opened the window to check, the cold air and noise that hit me was incredible.

I received the windows first thing this morning, and they are now installed they look good and do exactly what I wanted. I am very happy.

Our new secondary glazing has stopped all the drafts and cut down on a lot of the road noise, I was really impressed with how easy it is to remove the panel as well. I will recommend you to anyone else needing secondary glazing.

Simple to fit secondary glazing. Immediately noticed the difference in traffic noise from outside - so much quieter. looking forward to seeing the energy savings come the colder months.

I had a condensation problem in my downstairs cloakroom, so I tackled this first. The secondary glazing looked great and it solved the problem. You get expert help, they keep you up to date on delivery (always on time) and the end product is first class, at a fraction of the cost of new glazing. Highly recommended.

Good quality windows, acoustic glass does the job well. We fitted these ourselves, but the website and customer service team make sure you've been informed of everything you need to do to measure correctly and that you've chosen the right options for openings. Not the cheapest, but all in all great service, would recommend to anyone.

Fitted secondary unit supplied by clear view, it was very well made & a perfect fit & with the acoustic glass blocks out practically all traffic noise!! Very pleased.

I've just finished a self-fit project on our listed cottage, of a mixture of horizontal sliding and lift-out units. The team at Clearview were helpful and efficient throughout, fitting instructions and tips were comprehensive and clear, and phone queries were answered promptly, with helpful advice and suggestions. The resulting sound insulation is remarkable - we live next to a sometimes noisy pub - and the outside appearance is unchanged. Inside the finish is neat and one hardly notices that there is secondary glazing there. Very satisfied.

Excellent service form start to finish, we are really happy with our new windows, the house is now much warmer and they have really reduced the noise levels from a near by road. The whole team at Clearview were very professional, the fitters were great and the whole experience was efficient and the windows fitted within a month. I would highly recommend Clearview to anyone looking for secondary glazing.

Great company, speedy arrived is just about 2 weeks. Sound insulation and warmth is good. Love the website it gives you an accurate quote online - superb. Going to buy some more windows, had been worried about buying online - need not have worried!

Clearview Secondary Glazing

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.

A great success and are very unobtrusive from the inside and the outside they have made a huge difference to the heat in the rooms...the existing heating is now more than capable of heating the house. Many thanks for all your team's hard work in installing them so efficiently.

Installers were organised, efficient and tidy who never forgot that they were working in a home. They worked hard and as work in one room was completed they cleaned up and left that room tidy. They seemed to take a real pride in their work.

We’re really pleased with our glazing units already we can feel a difference with the ambient temperature in the house and in the reduction of draughts. Your fitters did a first class job in fitting the units. We’re now starting to look through the windows rather than at them! Your service has been exemplary throughout. Many thanks.

The secondary glazing looks great and the various styles used for different windows are very clever. They allow me to open the windows easily. Our house has been much warmer since the secondary glazing was fitted. We don’t have the heating on anywhere near as much, and have noticed that there has been a significant reduction in noise from the road.

5/5
Clearview Secondary Glazing

The window is perfect it cuts out all the road noise and has already made the room warmer. The design and workmanship are impressive. We have a listed building and even though the secondary glazing is a sash unit, it is invisible from the outside. Delivery was on the day promised and it took me just 40 mins to install. Congrats on a great product. I will be ordering more units.

Excellent service from this company and its staff. The manufacture, delivery and quality of the window was excellent and I fitted it with ease. (I’m an average DIY person). The pictures show how well it has covered a beautiful (but draughty) stained glass window

What the company offered was perfect for us because we wanted to retain the external character of our home, while keeping heat in, and noise out. Megan’s room is at the front of our house, and she has alway been a light sleeper, so sounds of cars and dustbin lorries were constantly waking her. But since the secondary glazing has been fitted she has slept much better.

The secondary glazing is now all installed and looks great but most importantly, at least for me, the noise insulation is amazing. I was troubled by an early morning diesel delivery van with a idling outside my house, but I’m not disturbed by it anymore! The windows were easy to install and look neat and in tune with my sash windows.

The windows look even better than I expected, and the impact on external noise reduction is immediately obvious. I’m sure they will make a significant difference to heat loss as well.
