440U
Polyurethane Insulated 1½” Commercial Sectional Door
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.

Panel Construction
The industry leader in innovative door safety, insulation, and strength
Increased thermal efficiency is achieved by a conduction-resistant thermal break.
Section joints are sealed with insulating foam and joint tape to reduce air flow.
Teinforced safety bottom brackets and red safety screws create a double layer of built-in safety.
A triple-reinforced steel fold extends across the entire section for solid hardware mounting, and an internal steel layer provides additional stability.
Perfected over generations, our precisely engineered polyurethane outperforms competitors in strength, energy efficiency, and density every time.
Our top-of-the-line galvanized steel is treated with a 4 layer process of a special high-strength, weather resistant finish.
Section Detail
The 440U panel texture varies based on the section design. The microgroove design has a stucco texture (interior and exterior) while the flush design has a wood grain finish on the exterior. Our door panels are constructed using top-of-the-line galvanized steel sheets that are treated with four layers of a strength and weather-resistant coating for a long-lasting surface finish and reduced maintenance costs.
Hörmann Innovations
Engineering Excellence
Our double end stile design adds to the overall structural integrity and long term performance of the door.
Note: Double end stile is available as an upgrade for all door sizes, but standard for doors over 16’2” wide.
Safety
The Hörmann 440U door comes with safety fixtures on the bottom sections for added peace of mind.
Quality in Every Layer
For maximum protection against the elements, a long lasting surface finish, and reduced maintenance costs, the door panels are constructed using a special bonding adhesive that is applied to the galvanized coated steel substrate, followed by a durable primer coating. The thick insulating core of high-grade CFC-free polyurethane rigid foam is injected evenly through a continuous computer-controlled process.
