Out-swing doors offer increased security, weather- and air-tightness, and durability. Whatever the specifications of the architect’s design, the Duratherm team will accomplish them. All of the same features for in-swing doors are available for out-swings.

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.
