Double Glazed Sash Windows

Yes, it is possible to have double glazed wooden sash windows!

Single glazed windows only offer limited insulation, while double glazing provides better thermal insulation, reduces energy bills and makes your home feel much warmer.

It is important to understand that not all double glazing is the same and does not offer the same level of thermal insulation. Our friendly experts talk you through the various 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.

  • 3 to 5 times more thermal insulation
  • Reduces heating costs
  • Provides a warmer environment
  • Complies with current building regulations
  • Improves security

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.
