Best Commercial Sectional Door Solution Based on Thermal Rating, Durability, and Maintenance 

Hörmann’s Best commercial sectional door solutions based on thermal qualities, durability, and maintenance, is the 440U (1½” thick, R-Value 15.7)  polyurethane insulated model.  The 440U doors are constructed using our environmentally friendly, proprietary blend polyurethane that is evenly injected between galvanized steel sheets via a continuous computer-controlled process.  Hörmann’s proprietary blend polyurethane has unmatched density and strength as compared to competitive brands. 

Our top-of-the-line galvanized steel sheets are treated with four layers of a strength and weather-resistant coating for a long-lasting surface finish.  A triple-reinforced steel fold extends across each panel section for added stability.  In addition, conduction-resistant panel thermal breaks along with foam / tape insulated joints reduce air infiltration and heat / AC loss.   

Only available from Hörmann, our reinforced safety bottom brackets and red safety screws provide an added layer of built-in safety.  Choose from four popular colors: white, brown, sandstone, or metallic silver (optional).  For ultimate customization, our Galaxy Paint System offers custom colors to match any color under the stars.
