All our windows are thermally efficient and it depends on your choice of double glazing product as to how much you could save on your energy bills.

You can get an idea of how much you could save by going to the trade association GGF (Glass & Glazing Federation) where there is a useful online calculator.

Triple glazing works in two ways, keeping heat inside your home and preventing cold from getting in from the outside using advanced technology.

It is usually most suited to the north facing elevation of your home as less heat will be coming into your home from the sun.

Triple glazing is also the best choice for sound insulation, meaning that it is particularly good for you if you live near an airport, busy road, or trainline. The extra layer of glass acts as an additional barrier, sound proofing your home.

We offer an extensive range of colours for our uPVC windows and you can also choose uPVC doors to match.

For more information on which colours are available for the products you have chosen, please contact us.
