425U
FingerGuard™ Polyurethane Insulated 1-3/4” Commercial Sectional Door
* This model is only available in the Eastern/Central US markets at this time
Highly Insulated 1-3/4” Polyurethane Insulated Commercial Sectional Door
Manufactured to the highest quality standards in the industry, all 425U doors come with Hörmann’s exclusive FingerGuard™ pinch resistant section joints.
The 1¾” thick door panel is constructed using our environmentally friendly, 100 percent CFC-free, proprietary polyurethane blend that is evenly injected between galvanized steel sheets via a continuous computer-controlled process. Galvanized steel sheets are treated with a bonding adhesive followed by a durable primer coating for a long-lasting surface finish. Standard panel design is shallow ribbed; smooth flush is optional. A deep tongue and groove section profile along with center hinges with steel reinforced backer plate, add to overall structural integrity of the door. Heavy-duty between-section-seals perform as gaskets between section seams, reducing air infiltration while enhancing insulating properties, achieving an R-value of 16.1.
White is the standard color, and for custom specifications, our Galaxy Paint System offers colors to match any color under the stars. Stainless steel accent designs are another available option for detailed customization.

Panel Construction
The industry leader in innovative door safety, insulation, and strength
Specially designed seals act as a gasket between sections to reduce the air infiltration while further enhancing the insulation properties.
Prevent fingers from getting caught between the door sections and reduces the risk of injuries and possible worker’s compensation claims.
Perfected over generations, our precisely engineered polyurethane outperforms competitors in strength, energy efficiency, and density every time.
Galvanized finished painted steel provides superior corrosion resistance for years of trouble-free performance.
Keeps out wind, rain, debris and other elements for added energy savings.
Section Detail
The 425U panel texture on both the shallow ribbed and flush designs have a stucco texture as standard. A smooth texture is optional on the flush design. 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
Hörmann's unique precision hinges with solid pivoting shaft minimize wear on moving parts for a long service life.
All center hinges have a steel reinforcing backer plate for added structural integrity, and a deep tongue and groove section profile adds to the overall structural integrity and longterm performance of the door.
Safety
Uniquely designed FingerGuard™ pinch-resistant section joints prevent fingers from getting caught between the door sections. This design promotes safety in your facility and reduces the risk of injuries and possible worker’s compensation claims.
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.
Superior Design
Standard section heights are 18” and 24” which allows for evenly placed ribs throughout the entire door height. The section joints appear seamless for a clean, balanced look on any style of building façade.
Exceptional thermal insulation properties combined with Stucco-textured exterior/interior surfaces, provide maximum protection against harsh environment and minimize the formation of water condensation on the interior door surface.
