Door Construction
-
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
