Type: Insulated Steel
When your major considerations include maximum energy efficiency, sound transmission, and aesthetics, Haas Door's MISER-THERM commercial insulated steel doors will far exceed your expectations. These CFC-free, polyurethane-foam-injected steel doors offer exceptional benefits for commercial applications.
These 1-3/8" thick doors have an excellent R-Value of 12.35. MISER-THERM doors use rigid vinyl extrusions with positive thermal breaks to eliminate metal-to-metal contact, which limits temperature transfer. Tongue-and-groove construction and section joint seals at meeting rails provide water and wind resistance.
A full-length, one-piece vinyl astragal retainer and flexible vinyl U-shaped weather-strip prevent infiltration of air, rain, snow, and debris. The seal fits to irregular or unlevel floors and reduces impact shocks when the door is closed against concrete flooring.Exceptional Strength
MISER-THERM doors are built strong. The high-density CFC-free polyurethane foam expands and adheres to the interior and exterior steel panels to provide a rigid unitized structure.
Our doors are reinforced with roll-formed galvanized steel struts and double-end hinges, as required to meet all local windload specifications.
Unique Paint System
Our three-tier, corrosion-resistant protective paint system is designed to resist even the most hostile weather conditions. The protective layers found on both the interior and exterior are:
The track is 2 or 3" galvanized steel, depending on door size, with bracket mount for wood jambs or continuous reverse mounting for steel jambs. For angle-mount track, door widths are 2" wider than opening. Track rollers are 2 or 3" case-hardened inner and outer steel races with 10-ball, prelubricated bearings. Hinges, brackets, and reinforced struts are hot-dipped galvanized steel, and fasteners are plated for maximum corrosion resistance.
Counterbalancing springs are torsion type, computer calibrated to match door load. This provides a 10,000 cycle life at the minimum; optional spring wires can achieve 25,000, 50,000, and 100,000 cycle requirements. Springs are wound from oil-tempered wire and mounted on a continuous cross header tube or solid shaft, as determined by torque load.
