Pour-in-place Perma-Buk Pro Hinged Window


We use Extra Thick PVC materials on all of our Perma-Buk Pro windows, and then fusion weld the frame and sash corners to assure years of trouble free performance. Our fully welded frames and sash assure that the weather will stay out and the corners will not "open up" over time as with mechanical fastened corners. Our windows are designed with 3/4" insulated glass, a sloped sill and fin-seal weatherstripping to provide an energy efficient combination. To make installation easier, our windows are fully assembled and braced to reduce your on-site labor costs. We even apply a protective film inside and out to prevent against frame damage during construction.


All of our Perma-Buk Pro Hinged windows feature an inswing friction fit hinge system and double lever handle sash locks for a positive seal and maximum security. All units feature an aluminum-framed, fiberglass mesh half screen.
