Garage Door System GuideRaynor builds insulated steel sectional doors for homes. Its lineup ranges from expanded polystyrene models to foam-in-place polyurethane doors like the Aspen AP200. Raynor documents thermal ratings, steel construction, and warranty terms on its product pages.
Aspen AP200 Construction and Thermal Rating
Raynor describes the Aspen AP200 as a polyurethane insulated door. The manufacturer lists NeuFoam polyurethane insulation with a tested U-factor of 0.17 and a calculated R-value of 18.0.
Raynor publishes the door's steel makeup as hot-dipped galvanized steel in 26-gauge. It specifies a 3-layer construction of steel, insulation, and steel, with a section thickness of 2 inches.
Insulation Options and Warranty
Raynor offers two core insulation systems. The manufacturer states that its polyurethane insulation is blown between the garage door's steel skins and expands to fill 100 percent of the door's interior space, with an R-value range of 12.0 to 18.0. Its expanded polystyrene insulation carries an R-value range of 5.0 to 10.25.
Raynor also notes a thermal break and air seal that prevent heat loss from metal-to-metal contact between inside and outside surfaces. On the Aspen AP200, Raynor backs the door sections with a limited lifetime warranty for single family residential use.
