Thermal Efficiency, Aesthetic Options, Long-Lasting Performance

When your project requires a thermal door that is as energy efficient as it is attractive, the Thermacore 594 Series is up to the task. These 1 3/8" thick doors provide high levels of thermal protection and are available in standard sizes up to 20'2" wide and 16'1" high. The 594 Series offers a raised-panel, wood-grain textured exterior surface. Fabricated using Overhead Door Corporation's proprietary, computer-controlled manufacturing process. The result is an exceptionally well-built door that adheres to the strictest product tolerances and quality standards - for long-lasting performance and good looks.

Strong, Lightweight, Attractive and Durable.
Thermacore 594 doors feature roll-formed, hot-dipped galvanized steel exterior panels. Two coats of baked-on, polyester paint - white on the interior and white or Chestnut brown on the exterior - provide a handsome finish that will last for years. Our 10-year warranty against delamination means that we'll stand behind the quality of our doors at the outset and for the long haul.

Superior Field Serviceability.
Thermacore's special internal construction allows hinges to be placed anywhere along the panel's length permitting customization on the job site - for fast and precise installation, repair or retrofit.

Highly Engineered for High Thermal Efficiency.
Thermacore's CFC-free, fully encapsulated, foamed-in place panel maintains R-value performance year round - and year in and year out. PVC thermal break and joint seals minimize air infiltration and provides one of the highest thermal efficiency ratings in the industry for its class.

Many Options, Better Solutions.
The Thermacore 594 is available in sizes up to 20'2" wide and 16'1" high. A full line of electric operators ensures precise and trouble-free motor operation in a variety of mounting options (side, center or trolley). Available options include aluminum sash sections up to 20'2", thermal glazing, and jamb weatherstripping. Optional high-usage components expand the door versatility to high-cycle conditions, with torsion springs in 25k, 50k, 75k or 100k cycles, a solid-steel shaft to reduce fatigue and deflection, and a heavy-duty 3" steel track for added durability.

Thermacore's steel-polyurethane-steel sandwich panel construction is lightweight, incredibly strong and exceptionally efficient - reflecting a level of thermal performance that is available only in Overhead Door Corporation's Thermacore line.
