Advanced Thermal Performance

This door system presents the most advanced thermal performance values published by any major US manufacturer of 3″ commercial insulated sectional doors, with a U-factor* of .07, R-value** of 26, and a tested installed U-factor† of .14.

The Thermacore^® AP 850 features superior construction, with a 3″ thick profile consisting of high-density foam injected CFC and HCFC-free polyurethane insulation. The polyurethane-insulated core offers the best insulation values per square inch.

Delivering further thermal efficiencies, the dual barrier tongue-and-groove joint profile (patents pending) creates a virtually impenetrable path for air leakage (air infiltration) in between door sections. This exclusive joint profile also serves as a true thermal break, 1-3/4″ wide, preventing front and back skins from transferring heat or cold. A second PVC thermal break further prevents heat or cold transfer at the end stiles.

Advanced Perimeter Protection

The Thermacore® AP 850 door system’s advanced perimeter design contributes to its overall superior thermal performance. A uniquely designed curved wall angle provides a tighter fit of the steel jamb seal to the wall angle, minimizing air leakage on the sides of the door system. This system also features top-to-bottom advanced perimeter protection, providing an air infiltration‡ rating at 15 mph of .09 cfm/sq ft (1.65 m³/hr/m²).

The header seal ensures a tight seal at the top of the door. The bottom weatherseal, featuring a rigid PVC retainer and dual durometer PVC bulb seal, locks out air and water leakage through the bottom section. The optional EPDM bulb seal is recommended for extreme weather conditions. Our patent pending enhanced thermal performance jamb seal combines an extended flapper and bulb seal in one unique design to complete the door system’s perimeter protection.

The Thermacore^® AP door system furnishes a Sound Transmission Class (STC)†† rating of 22, minimizing noise transfer through and around the door. The higher the STC†† rating, the better the buffering is from the transmission of sound through and around the door.

Flexibility in Design

The Thermacore® AP door system sections feature continuous steel strips that run along the width of each section which allows hinges to be placed anywhere along the section, unimpeded lite placement and easier center mounting of a trolley operator. Operation options include chain hoist and electric operator. The varied options of operation and mounting (left or right handed) afford flexibility to meet the needs of the facility and application.
