GHQ 320

With the benefits of the GHQ300, plus a heavy-duty 20-gauge exterior, the Garage Headquarters GHQ320 sectional insulated steel door is perfect for meeting job-specific requirements without sacrificing the features you expect from a commercial Garage Headquarters door.

Ideal for commercial warehousing, agriculture, fire station, and ambulance bays, refrigerated buildings, underground parking, and high-security facilities.

MAXIMUM THERMAL PROTECTION

Energy-saving polyurethane foam insulation is used to deliver an exceptional 24.54 R-value for the GHQ320.

DECREASED ENERGY COSTS

GHQ320 doors help you reduce energy costs with a U-shaped, vinyl bottom weatherseal secured by a sturdy aluminum retainer.

CHOICE OF WINDOWS

Select either 24″ x 8″ (shown), 24″ x 12″, or 34″ x 16″. GHQ320 doors are also available with aluminum full-view window sections.

Choose from a variety of insulated glass, acrylic, tempered, and polycarbonate styles to suit any application.

CUSTOMIZED TRACK AND HARDWARE SYSTEMS

Track systems are supplied to fit special clearances, inclines, or contour applications. Hardware and track systems can be designed to fit any need. Additional trussing is available for special wind loading applications. A QuikClip™ pre-assembled track option is also available.

HIGH-CYCLE COUNTERBALANCE SYSTEM

For reliable operation in high traffic areas, choose high-cycle torsion springs with 25,000, 50,000, or 100,000-cycle life.* For reduced maintenance and ultra-smooth operation in heavy-use applications, choose a weight counterbalance system.

*Some options may be limited to door size or model.

RUGGED HARDWARE AND SPRINGS

Your commercial Garage Headquarters door comes packaged with the right combination of long-lasting hardware, track, and springs to precisely match your door’s size and application.

REDUCED AIRFLOW

Dual vinyl barriers dramatically reduce air infiltration. A true thermal break prevents heat loss and eliminates any metal-to-metal contact between surfaces.

SECURE LOCKS

In applications where control and access are important, choose from a variety of locking options to help keep your building secure. Locks come in both inside and outside variations.

CARBON MONOXIDE VENT

Allows you to channel fumes to the outside when the door is closed. Available in a variety of sizes.
