Two-part foam ruined my trim job until I went back to wood shims
I had a project in St. Louis last month, 14 windows, and I tried the spray foam trick for setting jambs. Everything shifted overnight, gaps opened up, and I had to pull three units out and redo them. Went back to cedar shims and a 4 foot level, set all 14 in one day with zero callbacks. Is foam just for rough openings, or am I missing something?
