Clopay® Expands Commercial Model 3720 Sizes to Accommodate Wider Openings

May 21, 2014

Clopay is now offering its commercial Model 3720 premium-duty 2” polyurethane insulated steel door in widths up to 36’2” to accommodate large openings on warehouses, manufacturing facilities, pole barns and outbuildings.

The doors were previously only available in standard widths up to 32’2”. The maximum height offered is 24 feet.

Oversized Model 3720 doors are engineered to order and supplied with heavy-duty hardware and detailed shop drawings illustrating the proper positioning of support brackets and the counterbalance system during installation. Additional header support is also required.

The Model 3720 provides a durable, thermal barrier against extreme temperatures and weather. The three-layer Intellicore® construction features environmentally safe CFC- and HCFC-free polyurethane insulation foam injected between two layers of galvanized steel, with a thermal break, to provide an R-value of 18.4.

An optional 32”x 80” pedestrian pass door can be added to doors up to 16’ wide to save on heating and cooling costs by reducing the number of times the main door needs to be opened.

The interior and exterior door panels are primed and coated with a baked-on polyester paint finish for a durable, low-maintenance, rust-resistant surface. The doors are available in white and brown with optional windows.
