Why Double Glazing is So Effective with Insulation

double glazed windows and doors

Since time began, man had had this battle with the elements, and even though we build solid houses that can withstand the weather, glazed windows have always been a major source of heat loss. Aside from the roof, for obvious reasons, the windows offer an excellent escape route for the valuable heat you generate, and the arrival of double glazing, in the 1980s, heralded a new level of thermal insulation for the British homeowner.

Hermetically Sealed Units

So, how exactly does double glazing reduce heat loss by up to 60%? The answer is a hermetic seal that creates a vacuum in the cavity, and with silicone gel, there is no moisture, and more importantly, heat cannot travel through this, meaning a considerable reduction in heat loss through the glazed areas. Of course, changing the windows and doors on its own will not be enough, as you also need adequate roof insulation, as hot air rises. This can be achieved with rolls of fibreglass, and great care should be taken when handling fibreglass, but modern applications have the itchy substance enclosed behind a sleeve, making for easy application.

Composite Materials

With the glazed areas now protected, one must focus on the frames, and with uPVC, you have the ideal material. It will not fade, crack, or peel and comes in many colours, with a faux timber grain for rustic type properties, and with a galvanised steel inner frame, the units are very robust and the uPVC acts as a thermal barrier, keeping condensation at bay.

Online Suppliers

You might be looking for double glazed windows in Essex or Cambridge, and an online search will bring up a list of window companies – which will be long – as the industry is huge. Finding the right contractor is a matter of talking to potential suppliers, and look for one that spends time at the design stage, rather than trying to force you into a quick sale, and avoid any company that has been in business for less than 2 years, as this establishes reliability. The typical contractor would have showrooms, where the customer can actually see different window and door designs in a real life environment, something essential when deciding on replacements. Once a design is agreed upon, it’s a question of price, and they would likely offer home improvement loans, which are generally very low interest, but whether you decide to top up the mortgage or have enough put by, once an agreement has been reached, the contractor would send a qualified surveyor to take precise measurements of every aperture, then the fabrication process can begin. Usually, the units would be scheduled for installation within a few weeks, and a typical home would take 2-3 days to complete.

The only UK homes that do not suffer from this annoying phenomena, are double glazed properties, and you can finally throw away that cloth you keep on the window sill, as there is no condensation issues with double glazing.

The many benefits make for an attractive proposition, especially if the timber frames have seen better days, and with online suppliers of bespoke designs, you can transform your home.
