Doors
1
Weather Resistance
Composite rails protect the door at the top and bottom edges to help block
moisture that can wick into doors.
2
Security
An enhanced lock block combined with 1-1⁄4" engineered lumber lock stiles
increase rigidity and stability.
3
Durability
With very little maintenance, a fiberglass door can bring a home years of durability.
Unlike wood, fiberglass will not warp or rot. And, unlike steel, it will not dent or rust.
4
R-Values
Built with a polyurethane foam core, Therma-Tru fiberglass doors insulate against
cold and heat for exceptional energy efficiency, offering up to four times the
insulating R-Value of wood.*
