Energy Efficiency and Durability
H-400U doors offer 1-3/4" thick two sided steel ribbed sections and CFC free polyurethane insulation with an R value of 16.4 for exceptional energy efficiency and structural integrity.
The top and bottom of each section has a 1/8” gap between the two steel joints which provides a thermal break.
Polyurethane insulation is a two component bulk system. It is laid in during the manufacturing process and is self-laminating to each skin during a continuous curing cycle.
Twin Joint Seal
Sections are equipped with bi-directional twin seals.
||Steel Reinforcement Plate
Provides structural integrity and rigidity to each section. Insures solid attachment of hardware toeach section.
Embossed Exterior Surface
The exterior skin is made of 26 ga. galvanized steel in ribbed design. The exterior surface is painted with a two-coat paint system.
