Environmentally friendly polyurethane foam core is injected between 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


Engineering Excellence

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.


Superior Design

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.


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.


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.

425U Construction

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 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.
