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.
Hörmann Special Features
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.
Quality in Every Layer
The structural integrity of each 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.
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, 425U doors allow maximum protection against harsh environment and minimizes the formation of water condensation on the inside door surface.
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.
