How does timber retrofit double glazing work?

Our proven retroGLAZE^® solution for existing timber windows and doors involves removing your existing inefficient glass and replacing it with high performing, genuine double glazing. Timber is an excellent insulating material and we want to retain your timber joinery where we can.

We will modify your existing timber sashes (the window section that holds the glass) to allow for the new double glazing. New timber beads will replace any old putty, and the new glazing system will improve the structural integrity and durability of the windows.

By using as much of your existing timber joinery as possible, we are able to maintain the character of your home, without compromising its aesthetic. Once installed, the changes are hard to notice, giving you a solution that looks great, performs exceptionally and is built to last.
