DOOR CONSTRUCTION

Composite rails protect the door at the top and bottom edges to help block moisture that can wick into doors. Unlike wood, fiberglass will not warp or rot. And, unlike steel, it will not dent or rust - and requires little maintenance.

Our fiberglass door slabs are up to 30% more resistant to kick-ins than standard steel doors. Our doors feature an enhanced lock block combined with a 1-1/4" engineered lumber lock stile which increases rigidity and stability.

Built with a polyurethane foam core that offers up to four times the insulating R-Value of wood, Therma-Tru fiberglass doors insulate against cold and heat for exceptional energy efficiency.
