Wind load design available for usage in high-wind conditions. Two coats of baked-on, polyester paint on a ribbed, textured exterior surface provide a handsome finish that will last for years. Our industry-leading 10-year limited 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® has a special internal construction which 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.
