It is important to note that not all double glazing is the same, and there are different levels of thermal insulation. Our friendly experts talk you through the various different components that go into providing you with efficient double glazing.

Whatever solution you choose, your new double glazed sash windows will provide 3 to 5 times more thermal insulation than your current single glazed windows.

Our new double glazed sashes are fully painted and decorated in our own, in-house workshop. The paint finish is micro porous, using the latest paint technologies, which provides an extremely clean and smart appearance and allows the wood to breath and expel moisture – which minimises the risk of rot.
