Is it acceptable for a window installation (new home construction) to be installed in the folllowing manner: Vinyl window installed, THEN edges on exterior sealed with 3" foil tape serving as flashing all around? (then vinyl siding placed over)
As far as I was aware, I thought 4 inches of overlapping flashing were required to be installed BEFORE the window was put in place… This was confirmed by every window installation source I could find, but I thought to check here to see if maybe it was technically allowable (although not recommended).
Before I make the builder fix every window in the home (28 of them) I thought I would check first. I could not find tha name of the manufacturer name, or I would just cite their instructions.
