Environmentally friendly beauty.

Long Doors’ patio doors are beautiful. They’re energy efficient, too. All our patio doors are ENERGY STAR® qualified and are constructed with a 1 1/2″ thermal barrier riser. This feature enhances the energy efficiency of the doors and provides additional durability.

Steel doors are constructed out of hot-dipped, galvanized steel with a polyurethane core. The process gives the door extra strength and an R-value of 15.

We’ve earned the ENERGY STAR Sustained Excellence Award for Door Manufacturing for 10 consecutive years.
