Standard window gap allowed for window size

#1 Post by Jimmy » Tue Nov 10, 2009 9:21 am

I have customer window install and one of the windows is about one inch smaller than the existing window. Is this normal? Shall I have them to remake the window exact size? What's the standard gap allowed? Thanks! By Jimmy

ive been with the same window company for the last 17 years. we've always used the 1/4 inch difference method. frame measures 1/4 inch less than the rough opening, on all sides. in my opinion, 1/8 inch doesnt allow for much manuvering or very tight applications.

Depends how racked the opening is, however, we deduct one 1/4" from the width and the height of the RO. That is where I get the 1/8 on all 4 sides.
