At Timbawood we are usually asked how our windows can keep the heat IN – and we have a range of solutions to optimise that.
But what happens when temperatures rise and we need our windows to help keep the heat OUT?
Luckily, there are a range of solutions to help keep your home cool in our increasingly hot summers.
Firstly, you may have already noticed if you have double glazing, that double glazing is better than single glazing at keeping the heat out. If you touch a single glazed window on a hot day, the glass will feel quite warm.
This is because double glazing has an inert gas between the two panes of glass, which is a poor transmitter of heat. So when there is a temperature difference between the inside and outside of a building, either when the building is warmer than outside during the Winter, or colder than outside on a hot summer day, the gas helps prevent the heat transferring either way.
The more inert a gas is, the less heat will be transferred. That is why we choose particularly inert gases, such as Krypton and even Xenon, for our slim double glazing.
The other main factor is something called ‘solar gain’. Single glazing has high solar gain – meaning it lets a lot of heat energy from the sun transfer through the glass.
To reduce this, our double glazing has a Low E coating on the inner pane. Low E or ‘low emissivity’ glass is a type of coated glass which reduces the amount of solar gain compared to clear glass. The Low E coating helps to reflect the sun’s heat away from a building as well as helping to stop heat leaving a building in winter.
For commercial properties, or south facing homes with bifold doors for instance, it is possible to use ‘Solar Control’ glass to reduce solar gain even further to avoid overheating. This glass usually has a more mirror like, reflective quality or tint to it – often seen in office blocks and conservatory roofs, which feature a lot of glass and therefore rely on Solar Control glass to regulate the temperature.
As well as the glazing of a window, it’s also important to consider the flow of air on a hot day. If you have sash windows, be sure to open the top sash as well as the bottom sash – which will help to create a circular current of air, so that hotter air can flow out of the top sash as it rises.
Timber windows London
Are you looking to replace your timber windows? At Timbawood we specialise in the finest single and double glazed sash windows and casement windows for period properties in London and the Home Counties.
As experts in period, conservation and listed properties, all our windows and doors are handmade to order in our West London workshop, and combine authentic period design with cutting edge insulation and security features. We manufacture and install timber casement windows, sash windows, French doors, Front doors, bifold doors and internal doors.
We also offer heritage window repair. If the window frames are in good enough condition, we can replace the moving sashes or casements only – and can replace single glazed sashes/casements with double glazed. One of our most popular products are double glazed sashes fitted with slimline double glazing, which looks just like single glazing.
