Fiberglass Doors
Fiberglass is virtually maintenance-free and holds up under extreme weather and temperature fluctuations. Our proprietary Ultrex® fiberglass is 8x stronger than vinyl and 3x stronger than vinyl/wood composites. This Marvin specialty helps our doors resist leaks, seal failures, and stress fractures. Put our decades of fiberglass development to work for you with our Modern, Elevate, and Essential doors, which feature either Ultrex or high-density fiberglass.
