Unmatched Energy Efficency and Durability
Hörmann H-425U offers 1¾” thick two sided steel sections and 100% CFC-free polyurethane foam core insulation for maximum protection against the elements. (R-value 16.1) Manufactured to the highest quality standards in the industry, all H-425U doors come with Hörmann exclusive FingerGuard™ pinch resistant section joints.
Ultimate Energy Efficiency
Highly energy-efficient polyurethane foam core. Environmentally friendly polyurethane foam core is injected between 25 gauge galvanized steel sheets front and back. This provides maximum insulation for substantial energy savings and ultimate panel stability for extremely quiet door operation.
Unique precision hinges with solid pivoting shaft to minimize wear on moving parts to provide long service life. All center hinges utilize a steel reinforcing backer plate for added structural integrity.Deep tongue and groove section profile adds to the door’s overall structural integrity and its longterm performance.
The uniquely designed FingerGuard™ pinch-resistant section joints prevent fingers from getting caught between the door sections. This increases the safety of your facility and reduces the risk of injuries which may result in worker’s compensation claims.
H-425U’s standard section heights, 18” and 24” allow evenly placed ribs throughout the entire door height. The section joints appear seamless and offer a clean and balanced look to any building’s exterior. With high thermal insulation properties and Stucco-textured exterior/interior surfaces, H-425U doors allow maximum protection against harsh environment and minimizes the formation of water condensation on the inside door surface.
Quality in Every Layer
The structural integrity of each H-425U section is enhanced inside and out to offer maximum protection against the elements to provide you with a long lasting surface finish and reduced maintenance cost. The bonding adhesive 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 in a continuous computer-controlled process.
Deep tongue and groove section joint contribute to the door’s excellent strength. Intermediate seals prevent air infiltration, which enhances the insulation properties.
Environmentally friendly polyurethane foam core is enclosed by 25 gauge galvanized steel on the inside and outside. This provides maximum insulation for substantial energy savings and ultimate panel stability for luxuriously quiet door operation.
Stucco-textured surfaces and high thermal properties minimize the formation of water condensation on the inside door surface
The bottom weather seal keeps out wind, rain, debris and other elements for added energy savings.
