340S
Commercial Insulated Steel Sandwich Door 1½"
Hörmann 340S standard duty commercial doors are insulated as standard.
As with all our commercial models, traditional Hörmann quality is evident with our layered panel bonding construction process. First, hot dipped galvanizing is applied to the steel substrate, followed by a baked-on polyester base coat, then a durable baked-on polyester finish coat. This layering creates a long-lasting surface finish for maximum protection against adverse effects of the elements. This steel finish is applied on both the inside and outside door skins which are then bonded to a HCFC-free polystyrene core. The 340S has a U-Factor of 0.29 and an R-value of 9.0, enhanced energy efficiency and sound-dampening are achieved. A polystyrene insulation fills the top of the door channel for maximum insulation.
Our optional double end stile design along with thermally broken tongue and groove section joints add to overall structural integrity, and standard bottom section safety fixtures contribute to safety. The 340S is available in white, brown, sandstone, black, or silver metallic.

Panel Construction
The industry leader in innovative door safety, insulation, and strength
Our precisely designed thermally broken section joints reduce air infiltration and create a weather tight seal.
A 3-layer steel front and back construction with insulating polystyrene core increases energy savings.
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 340S panel texture varies based on the section design. The microgroove design has a stucco texture while the flush and raised panel designs have a woodgrain finish. 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
Hörmann 340S doors come with safety fixtures on the bottom sections for added protection and peace of mind.
Durability
340S door panels are prepared inside and out for maximum protection against the elements, a long lasting surface finish, and reduced maintenance costs. The door panels are constructed with application of hot dipped galvanizing to the steel substrate, followed by a baked-on polyester base coat and a durable baked-on polyester finish coat.
