Model 850 

advanced sectional door

The Thermacore® AP Model 850 is engineered to deliver advanced performance in commercial and industrial applications where climate control, durability and ease of maintenance are primary concerns.

The Thermacore® AP door system’s advanced performance answers the demand for more reliability, durability, design flexibility and thermal efficiency.

This door system presents the most advanced thermal performance values published by any major US manufacturer of 3" commercial insulated sectional doors with an R-value* of 26, U-value** of .038 and a tested installed U-factor of .14.

* R-value is a measure of thermal efficiency. The higher the R-value the greater the insulating properties of the door. Overhead Door Corporation uses a calculated door curtain R-value for our insulated doors.

**U-value is a measure of the flow of heat through an insulating or building material; the lower the U-value, the better the insulating ability. U-value is the inverse of R-value.

† Installed U-factor is a tested value of actual energy loss - whether heat or cold - of an installed door, wall, or window assembly (calculated per ASHRAE). The lower the number the lower the energy loss and therefore the better the thermal performance. For best U-factor, choose finish and color with high solar reflectance (bright colors).
