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
