How to make a WINSERT (winter insulated window insert)
Method adapted and developed by Brian Nugent, 2007
NOTE – most of us at NQE no longer use this method of film installation (we like the “wrap” better), but Brian has some very useful instructions here for measuring and making the frame, shrinking the film, and applying the foam tape.
