I'm about to fit a couple of new UPVC windows into brick openings. I remember reading somewhere that it's not a good idea to use standard expanding foam for the gap between the frame and brickwork, because it expands too much and can distort the UPVC frame.
I seem to remember them suggesting a foam that doesn't expand quite so much. Can anyone recommend one, or am I worrying to much about this?
Thanks for any advice and help.
