Lift/Roll Doors
Quality construction, thermal integrity and ease of use are standard characteristics of our lift and slide doors.
Our hardwood frames create strength and durability. Our custom hardware is engineered to provide almost effortless movement — even in the heaviest constructions — by lifting the door onto its carriage and rolling or sliding the panels to open. The hardware also allows for positive stopping at all intermediate openings. Custom built to any size your designs call for, these doors instantly become a signature in the homes and buildings where they are used.

Glazing Configurations
All types and configurations are available to use in Duratherm windows and doors. From single monolithic to triple glazing, laminated, curved-in-place, electrochromatic switchable – virtually any type or configuration commercially available – and perhaps even some that are not.
Glazing Methods
Dry Glazing
Specially developed extruded silicone gasket sets the glass by compression. Our proprietary system is long-lived, has low maintenance, and stays 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.
