With the VELUX 10 year guarantee you know you have the best service possible, with the reputation to prove it. Replacement VELUX provides better heat and sound insulation properties by upgrading existing glazing units from older windows manufactured before April 2001. The brilliant thing about VELUX is that they have not changed the standard window sizes for 40 years. So if you are looking to replace the glazing only then all you need to do is provide us with the code found on the metal strip on the top inner edge of the window frame. You can click here for a better direction on where to find this.
Replacing these old roof windows using the VELUX replacement panes enhances the window and improves its performance.
We do advise that if you need to replace your window then you should also replace the flashing as this will ensure the thermal performance of the window and remove the risk of old flashings leaking.
