Understanding the science behind double glazing

We’re living in an era when science surrounds us in our homes, cooking our food, keeping us warm and allowing our homes to be energy efficient. Your windows are a key part of this, because their job is to retain heat in the house and keep cold out of the house, making the house much more fuel-efficient and reducing energy bills.

You’ll know if your house is in need of double glazing, because you’ll actually feel draughts as the winter gales set in. You’ll find that you need to run your heating continually, because heat is being lost all the time, instead of being able to run it for a while then turn it down. Of course, you’ll notice the resulting energy expenditure on your bills.

According to Firmfix, specialists in double glazing in Cheltenham, windows that were installed some time ago may well have lost efficiency and become misted, so it may be time to think about new and more efficient windows.

Modern double glazing insulates your home

The Energy Saving Trust explains that many manufacturers of windows display how energy-efficient their products are, by using a rating scale which goes from E (not very efficient) to A+ plus (the most efficient you can have). This scheme assesses the whole of the window – that is, both the glass and the frame. So this is definitely worth checking out if you are thinking about new double glazing.

The science behind double glazing

Double glazed windows have two glass panes which have an airtight gap between them. The gap is too small for air to circulate through and this slows down the transfer of heat from the warm inside of the house to the cold outside. So a smaller amount of heat lasts for longer. Firmfix provide double glazing in Cheltenham and can give you an estimate of how much you would probably save with double glazing, if you don’t have it currently.

The airtight gap is crucially important to delivering the heat saving of these windows. So if you have noticed misting or condensation – and this is seen quite often in double glazing in Cheltenham – the seals that keep the gap airtight might have failed, and it is certainly time to upgrade your windows.

There’s still time to reap the savings from new double glazing this winter.
