Wood Species & Finishes
Duratherm sources all materials by project — from only providers we know and trust. Many of our woods are from Forest Stewardship Council® (FSC- C108949) certified sources. We obtain others from sustainably harvested plantations. Fourteen domestic and exotic wood species offer a wide range of colors, grains, and textures.
Please contact us for information about finishing options (including paint, Sikkens, clear laquer, stain, bleach stain, oil, etc.) and to discuss the use of a species not in our standard offering. We consider availability, durability, machining, and gluing characteristics to determine the feasibility of your choices.

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