Fixed Frame Windows
A fixed frame hardwood window, known commonly as a picture window, is a non-operable window that creates the appearance of a picture frame on the wall. They are commonly installed as a single window or used in combinations with more functional window types creating a spectacular window wall. These hardwood windows are always custom built to your precise specifications to help bring your vision to life. Create a unique appearance from the interior and exterior with large and flat glass surfaces.

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
