Extra UPVC Frame Extenders

A frame extender allows to increase the thickness of your window/door at any side. Great for properties with deep plaster, render or tiles over tiles. 25mm or 40mm extensions available.

Some fitters buy extenders as a precaution, for example where the window opening has not been built yet. Extenders can be modified to accommodate inconsistent side walls.

Extenders simply clip or slide on the window profile as you can see on the video.
