Thermacore® Sectional Steel Doors 591

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​When your project requires a sectional door with an exceptional degree of thermal efficiency, the Thermacore® Sectional Steel Door Model 591 is a proven performer. The Thermacore® steel-polyurethane-steel panel construction provides a thermal barrier that withstands extreme climatic conditions and the most demanding environmental requirements.

This 1 5/8” (41 mm) thick, heavy duty door fits a wide range of opening sizes and the spectrum of applications — making it the best-selling door system in the Thermacore® line and one of the most-specified insulated sectional doors in the industry. Boasting an R-value of 14.86 (2.63 W/m2), a U-value of .067 (.380 m2/W), and one of the best air infiltration ratings, the Thermacore® 591 will meet or exceed almost any thermally efficient application requirement.
