A Benchmark door protects a property from the elements and from intruders. The Benchmark GRP door combines the very latest technologies to produce an industry leading product.

The GRP facing (Glass Reinforced Plastic) looks like wood but is unaffected by variations in temperature. When combined with a modern sub-frame, insulating core, modern outerframe and a fantastic hardware range, the Benchmark door delivers a high security, weather-tight door that will not bow, warp, crack, splinter or dent. Combined with side and top lights, a Benchmark door provides stunning looks that will add instant appeal to any home.
