*Wayne Dalton uses a calculated door section R-value for insulated doors.
Joint seals prevent air infiltration and saves energy
Thermal break separates inner and outer skins so virtually no head or cold is conducted through the section.
Pre-painted inner and outer skins for added corrosion resistance
Solid polyurethane core provides maximum thermal efficiency and aids in quiet operation
Integral struts – Two 1-3/4” roll-formed struts per section increase rigidity and strength.
Two-inch nominal thickness
Heavy-duty 20-gauge smooth flush exterior skin gives the Thermospan 200-20 added strength and makes it ideal for large openings
The Thermospan® 200-20 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® 200-20 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.
