Windows & Door fitting

Fitting Double Glazing

Anonymous user 23/02/2024 - 2.43 PM

Hi, I have just had some windows fitted which I have serious concerns over. I noticed the fitter using just foam to secure a window, should I be worried about this? He said this is the only window he has done this to, as the exisiting frame was rotten, he mentioned this was the only way to fit this window. He also mentioned that the other windows have been secured to the exisiting frames and this is the only one he has fitted this way. This is the only frame I witnessed going in so I have serious concerns. If the window has just been fixed with foam, does this not represent a serious security risk?

Are you a tradesperson and able to answer this question?

current local regulations and FENCA state all frames must be securely screwed

Hi There This unfortunately is not the proper method to fit windows, the principle function of the expanding foam is to ensure that no gaps are left when the window is fitted, it should not be used as a method of anchorage and mechanical fixings should always be employed The ability of the foam to secure a window in place depends upon its adhesion to both the window material and the opening into which it is being installed, if there is poor adhesion then a wind-load on the window could theoretically break the seal and loosen the window, this would be more likely with larger windows which provide greater surface area, if the window is “foamed” only then it depends on the foams adhesion for its security This is common enough practice, and thankfully in most cases it does work, but its neither a method that we employ or encourage Many Thanks Ken Clydebuilt Joinery
