*Wayne Dalton uses a calculated door section R-value and U-value for insulated doors.
**Thickness measured at heavy-duty end stiles
Thermal break separates the inner and outer skins at the top and bottom so virtually no heat or cold is conducted through the section.
Patented foamed-in-place technology bonds the polyurethane core to hot-dipped galvanized inner and outer skins, creating a door that is significantly more efficient than conventional insulated steel doors.
Flush door embossed pinstriping (grooves) on the outer skin adds strength.
Prepainted inner and outer skins are hot-dipped galvanized steel for added corrosion-resistance.
Roll-formed integral struts add rigidity and strength.
18-gauge “wrap-around” end caps offer interior hinge attachment surface and exterior leg for proper seal against jamb.
Joint seal prevents air infiltration and helps save energy.
The Thermospan® 150 meets IECC® requirements for maximum U-factor of operable fenestrations (2015 Section C402.4) with a 3rd party certified tested value of less than 0.37. Thermospan® 150 also meets the ASHRAE 90.1 and IECC® requirement for maximum air leakage for fenestration assemblies (2015 Section C402.5.2 Garage doors) with a 3rd party certified tested value of less than 0.40.
