Regardless of the options you choose, you can trust that your patio doors will be installed by only expert technicians and that they’ll provide you with flawless functionality and beauty for years to come.

Environmentally Friendly Beauty

Not only are Long Doors patio doors beautiful, but they’re energy efficient as well. In fact, all our patio doors are ENERGY STAR® qualified and are constructed with a 1 1/2″ thermal barrier riser. This feature not only enhances the energy efficiency of the doors, but it also speaks to durability since it will not rot or warp over time. Steel doors are constructed out of hot-dipped, galvanized steel with a polyurethane core, which in addition to providing extra strength, also gives the door an R-value of 15. It’s benefits like these that have allowed us, in conjunction with ProVia, to receive the Environmental Protection Agency’s s ENERGY STAR Sustained Excellence Award for Door Manufacturing for five consecutive years.
