Warm Springs Composite Products patented FRX series of fire-rated composite or wood door frames allow architects and contractors to comply with the strictest of fire ratings without compromising the aesthetic appeal of natural wood finishes. The frame's unique design allows it to achieve required fire ratings with both neutral and positive pressure testing. WSCP frames meet U.S. standards for 20, 45, 60, and 90-minute fire ratings with certification provided by Intertek Testing Service, UBC 7-2 (1997)/UL 10(c) (1998). WSCP also holds certifications to meet British Standard 476, part 22, up to 120 minutes and BS EN 1634-1; 2014 up to 3 hours.

WSCP fire-rated frames are sold through a network of remanufacturing companies that have been certified by Intertek testing Systems and approved by Warm Springs Composites to use WSCP's rated constructions to properly machine and finish the frames. Fire-rated frames are available in an unlimited assortment of hardwood and softwood veneers, as well as paint grade and high pressure laminates to match the doors, wood casings, and trim throughout the interior space. The frames are available as single or double rabbet, for single or paired openings, as well as communicator frames. Moisture resistant substrate is available on request.

WSCP's frame design incorporates intumescent material concealed in the frame itself, thereby eliminating the need for intumescent in the doors. This results in significant cost savings without compromising the ability for the opening to achieve the necessary fire-rating. An available patented adjustable clip system allows for simple and quick installation, saving the contractor both time and money. The frames can be installed using traditional methods as well.

WSCP frames are certified under ITS approvals to achieve positive or neutral pressure 20, 45, 60, and 90-minute ratings in openings up to 96" x 96" with wall thickness of 4.5 inches or greater. Call WSCO for details on British Standards.
