Fixed Frame

A fixed-frame window creates a view frame almost like a picture on the wall. Installed as single windows or in a spectacular window-wall, these hardwood windows, always built to custom specifications, can build a unique appearance from the outside and a very special environment on the inside because of the larger flat glass surfaces. The nature of fixed-frame windows means that they are often used in combination with other more-functional window types.

FEATURES

Wood Species & Finishes

Duratherm sources all its materials by project, only from providers we know and trust. Many of our woods come 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 on our standard menu. We consider availability, durability, machining, and gluing characteristics to determine the feasibility of your choices.

Glazing

We offer dry or wet weeped

glazing compounds.

Specially developed extruded silicon gasket sets the glass by compression. Our proprietary system is long-lived, has low maintenance, and stays waterproof.

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