Standard Practice for the Installation of Mounting Flange Windows into Walls Utilizing Foam Plastic Insulating Sheathing (FPIS) with a Separate Water-Resistive Barrier (WRB), FMA/AAMA/WDMA 500-16

Reference

Guide describing the installation of windows in walls that have foam plastic insulating; guide provides several methods for attaching, supporting, and flashing windows in walls with rigid foam sheathing. (Note: The link only goes to the table of contents for the guide, the full guide can be...

Even with R-30 of insulation in the wall, its overall R-value is R-5 if it has single-pane windows; triple-pane windows bring that up to R-16

A dormer with an openable window (not shown) can provide access to the roof if flood waters rise too high and too quickly; the dormer should be properly insulated, flashed, and air sealed

Image

Once window trim is removed around window, any fibrous insulation is removed and the opening is brushed before installing canned foam or backer rod and caulk to air seal the rough openings
