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 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.
