Clopay® Introduces Commercial Model 3724 2” Polyurethane Insulated 24 Gauge Overhead Sectional Steel Door

May 21, 2014

Clopay is introducing a premium-duty 24-gauge overhead sectional steel door with an R-value of 18.4 to its 2” polyurethane insulated commercial door line.

“The Model 3724 takes the industry’s conventional 24 gauge specification to a new level of thermal efficiency, durability, and safety,” says Jim Hoying, Clopay’s commercial business development manager.

“Historically, 24 ga steel doors for warehouse applications have been pan doors insulated with sheets of polystyrene or isocyanuarate.  The Model 3724 is a three-layer steel “sandwich” door.  CFC- and HCFC-free polyurethane is foam injected between two hot-dipped galvanized steel skins, creating a solid, bonded core for maximum energy efficiency and strength.”

The sections have a continuous thermal break to prevent the transfer of hot or cold air from outside indoors. An optional 32”x 80” pedestrian pass door can be added to help maintain a consistent temperature in the building by reducing the number of times the overhead sectional door needs to be opened.

Building owners can reap additional cost-savings and increase the life of the door by specifying Clopay’s re-settable, break-away bottom section for doors installed in high-traffic loading dock areas. If the door is accidentally struck by a forklift or another piece of heavy equipment, the section gives way and can be reset in a matter of seconds, eliminating downtime and costly service repair calls, as well as reducing operator injury and impact damage to the building’s structure.

The break-away bottom section matches the exterior appearance of the door creating the illusion of a continuous door for added security.

The Model 3724 is available in door heights ranging from 6’3” up to 24’ and widths ranging from 9’2” up to 32’2” long, in five colors: white, brown, tan, gray and Trinar® white.  The interior and exterior hot-dipped galvanized steel panels are primed and coated with a baked-on polyester paint finish for a durable, low-maintenance, rust-resistant surface.

Hardware includes a full-length vinyl astragal, 14 gauge hinges, commercial 10-ball steel rollers, and 25,000, 50,000 or 100,000 high cycle torsion springs. Various window options are also offered.
