Therma-Tru Benchmark Fiberglass Door vs MMI Door Fiberglass 4-Lite Front Door
The Therma-Tru Benchmark is the stronger door for storm-prone coasts and for anyone who wants a finished, painted Shaker look out of the box. It is impact rated for large missiles, rated for Wind Zone 4, and carries a composite frame and edges that resist rot. The MMI Door 81.75 in. fiberglass 4-lite is the simpler pick for a covered, milder-climate entry where four clear glass lites and an Energy Star label matter more than impact ratings. Owners of fiberglass doors in this class report they hold paint and resist warping better than wood or steel, though both need a good seal and proper flashing to stay dry.
- Choose the Therma-Tru Benchmark if you live in a high-wind or hurricane zone, want a prefinished Shaker door with Low-E glass, or need a composite frame that will not rot.
- Choose the MMI Door 81.75 in. fiberglass 4-lite if you want more daylight through four clear glass lites and an Energy Star door for a sheltered entry.
