Glazing

Dry Glazing

Specially developed extruded silicone gasket sets the glass by compression. Our proprietary system is long-lived, low maintenance and warer resistant.

Wet Glazing

Our special silicone wet glazing compound bonds to the glass for long-lived sealing. Plus, our continuous extruded silicone weatherstrip runs around the frame perimeter and the seal is not compromised by seasonal expansion and contractions of the sash and frame.
