Materials & Construction
Wayne Dalton’s Thermospan® 125 doors feature continuous foamed-in-place polyurethane insulation and standard joint seal that provide an R-value of 10.79. The construction provides a substantially higher thermal efficiency than industry standard polystyrene doors.
Thermospan® 125 doors feature pre-painted inner and outer skins made from hot-dipped galvanized steel for added corrosion protection. The exterior surface is pebbled and grooved, enhancing the appearance while providing improved strength. The Wayne Dalton Thermospan® Series doors are the only doors in the industry with two patented, 1 3/4"roll-formed integral struts on each section, making them the most rigid doors available.
Hot-dipped 18-gauge galvanized end caps offer a superior surface for hinge attachment. Our standard joint seal prevents air infiltration and in conjunction with the solid polyurethane core, offers enhanced energy efficiency.
*Wayne Dalton uses a calculated door section R-Value for insulated doors.
