Thermally Efficient Flush Sash Windows


When looking to save money the first place you might think of reducing is your energy bills. Unfortunately, with underperforming double glazing, your home could be subjected to drafts and cold spots that require you to keep your heating on high.

Our flush sash windows are designed to keep your home warm and comfortable. These profiles keep out the cold and windy weather to keep you and your family cosy during those winter months. Rated by BFRC – our flush sash windows have an ‘A’ energy rating.

Double glazing works by having a layer of argon gas trapped between two panes of glass. This creates a thermal shield as argon gas is a poor heat conductor. This will, in turn, stop your heating from escaping, essentially trapping it in your home.

Save money on your energy bills and reduce your carbon footprint with these flush sash profiles from Timeless.
