Insulated Sectional Steel Door

Wayne Dalton Thermospan® Model 200 provides premium thermal efficiency and low maintenance costs, resulting in a door that costs less to own.  Continuous foamed-in-place polyurethane insulation and a non-conductive thermal break between the inner and outer skins combine to provide a U-value* of .057 and an R-value* of 17.50

The Wayne Dalton Thermospan® Series doors are the only sectional doors in the industry with patented, roll-formed integral struts on each section, making them the most rigid doors available.  The Thermospan® Series also has a patented manufacturing process with a polyurethane core that is continuously foamed-in-place between the outer and inner skins.  An innovative thermal break keeps the interior skin at room temperature, preventing condensation and frost and helping to resist corruption.

*Wayne Dalton uses a calculated door section R-value and U-value for insulated doors.

Door Construction:

1. Joint seal prevents air infiltration and saves energy.

2. Thermal break separates inner and outer skins so virtually no heat or cold is conducted through the section.

3. Pre-painted inner and outer skins for added corrosion resistance.  Both skins are also hot-dipped galvanized steel for further protection against corrosion.

4. Solid polyurethane core provides maximum thermal efficiency and aids in quiet operation.

5. Integral struts - Two 1-3/4" roll-formed struts per section increase rigidity and strength.

6. Two-inch nominal thickness.

7. Embossed pinstriping (grooves) on the embossed stucco outer skin adds strength and enhances appearance.

IECC® Compliant:
