Quality construction and thermal integrity, plus ease of use are all standard characteristics of our rolling doors. Hardwood frames create strength, durability and low maintenance. Custom built to whatever sizes your designs call for, these doors become signatures in homes and buildings. Our custom hardware is engineered to provide almost effortless movement, even in the heaviest constructions, and allows for positive stopping at all intermediate openings.

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.

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.
