Our Slide Fold door systems enable expansive walls of glass to open up for clear unobstructed openings. Optional flush sill detailing helps create a seamless transition from interior to exterior. These door systems are popular for restaurant facades, pool enclosures, and porches, providing a spacious, wide open feel to any space.
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.
EXTERIOR WOOD SPECIES
INTERIOR WOOD SPECIES
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.
