Clopay^® Commercial Model 3720 Energy Series Door Now in Sizes Up to 40’2” Wide with New High-Performance Hardware Kit

CINCINNATI (September 29, 2017) -- Clopay is now offering its commercial Model 3720 Energy Series 2” polyurethane insulated steel door in widths up to 40-feet, 2-inches and heights up to 26-feet for large openings in a variety of applications, including agricultural buildings, construction machinery and equipment facilities, and aviation warehouses.

The Model 3720 provides an energy-efficient 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. 

The polyurethane foam insulation fills the entire steel frame making the door stronger and quieter. 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.

Doors 36’2” and wider come standard with Clopay’s new High-Performance Hardware. Designed to meet the extreme demands of a larger, heavier door in high-cycle environments, High-Performance Hardware kits include 3” sealed rollers with a 5/8” diameter stem, 10-gauge steel end hinges, and heavy-duty top brackets. 

The High-Performance end hinge features a proprietary graduated design that can be adjusted to fit the roller position as needed, depending on where the hinge is placed on the door.

“The versatility of the adjustable design means our dealers require less hinge inventory for the installation or service of large commercial doors. Two hinges cover a wide range of sizes, from 3 to 7 and 8 to 14,” says Dylan Fransen, Clopay commercial marketing manager. “Our High-Performance Hardware exceeds industry standards for strength and durability. Clopay is the only manufacturer offering commercial hardware of this kind.”

High-Performance Hardware can be purchased with doors, or separate as a service kit for existing doors.  

Clopay Model 3720 complies with the 2015 IECC (International Energy Conservation Code) with an air infiltration rating of .40 cfm/ft. or less (IECC, Section 402.5.2) and also meets the U-factor requirement of .37 or less (IECC, Section C402.4, for Climate Zones 1 through 8.)
