Taking the Wraps off of Thermosteel

IMPERIAL TAKES THE WRAPS OFF OF THERMOSTEEL COLD STORAGE DOOR HARDWARE BACKING SYSTEM

Portland, OR - In May of 2007 Imperial Manufacturing unveiled a new insulated steel door backing system for mounting refrigeration door hardware. The traditional manufacturing method for fabricating steel door backing for refrigeration hardware calls for the steel backing to be mounted behind the exterior finished metal skin on the door frame. The door hardware is then to be attached directly to the exposed side of the exterior finished metal skin and attached directly to the interior steel door backing.

Steel door backing is the strongest and most durable method to mount refrigeration door hardware. One drawback to the traditional steel door backing systems are that the steel backing promotes premature corrosion through electrolysis when used with certain exterior finished metal skins, such as aluminum for example. Another condition is created through the conduction created between the two metals contacting one another in cold storage/ambient air conditions. The conduction between these two metals will cause it to sweat and eventually stain and rust the finish metal on the door and frame. This is usually referred to as “telegraphing.”

The ThermoSteel door hardware backing system incorporates the use of 1/2” thick Thermo-Lite ® insulated boardstock sandwiched between the cold storage door hardware and 10 gauge galvanized backing plates. The remainder of the cavity inside the door and frame sections are foamed in place with urethane foam. The Thermo-Lite® board acts as an isolator between ferrous and non-ferrous metals eliminating any chance for electrolysis to occur. The insulating value of the Thermo-Lite® inhibits conduction from cold transfer between the backing plates and the finished wall metals. This will eliminate any rust or corrosion from forming on the exterior finished wall metals. The Thermo-Lite® composite material is present throughout the entire door frame section and provides superior strength without the use of conductive materials attached directly to the door hardware.
