Materials & Construction
The Model 220 door uses “C”-shaped 20-gauge center and 16-gauge end stiles which are formed of galvanized steel with prelocated extruded holes for rapid hinge attachment. Optional 16-gauge center stiles are also available.
Bottom sections feature a flexible bulb-shaped vinyl astragal held in place by a continuous roll-formed steel retainer that reinforces the lower portion of the door at the same time.
Additional options include top head seal, joint seals and jamb seals. Optional insulation, consisting of 1 5/16” expanded polystyrene or urethane and covered with .022” minimum embossed pre-painted white steel provides an R-value of up to 7.64 and a U-value as low as .013. Lite options include insulated or non-insulated factory-glazed lites or complete aluminum full-view sections for maximum visibility. Operators can also be specified for use with the Model 220.
