A total of 116 doors, including a combination of Model 3717s and Model 3720s with pass doors, are being installed in three buildings to act as a thermal barrier against extreme temperatures and weather.
The Model 3700 Series three-layer “sandwich” doors feature environmentally safe, CFC- and HCFC-free polyurethane insulation foam injected between two layers of galvanized steel, with a thermal break, offering R-values of up to 17.2. There are five models available in 1-3/8”, 1-3/4” and 2” panel thicknesses. Four color choices and a variety of glazing options are also offered.
A 32”x 80” pass door is an option on the Clopay Model 3720 for applications that have pedestrian traffic, and saves on heating and cooling costs by reducing the number of times the sectional door needs to be opened. The pass door is also with continuous geared hinge reinforcements for added strength and smoother operation.
