This sectional insulated door system is one of the finest [advanced sectional doors](https://www.overhead-doors.com/commercial-doors/advanced-sectional-doors) on the market today. Engineered to deliver advanced performance, this industrial door is ideal for situations where you need climate control, durability, strength, and an easy-to-maintain system. This [Thermacore® door](https://www.overhead-doors.com/commercial-doors/thermacore-doors) is a 3-inch-thick insulated sectional door that is rated one of the strongest and most thermally efficient doors on the market, offering the best insulation value per square inch.

[![Thermacore_AP_Door_850_Series](https://www.overhead-doors.com/hs-fs/hubfs/Thermacore_AP_Door_850_Series.jpg?width=280&name=Thermacore_AP_Door_850_Series.jpg)](https://www.overhead-doors.com/overhead-door-blog/thermacore-ap-door-850-series)[Sectional Thermacore AP 850 Series](https://www.overhead-doors.com/overhead-door-blog/thermacore-ap-door-850-series)

Additionally, the door is constructed with a dual-barrier that creates a virtually impenetrable path for air leakage and infiltration between door sections, and PVC thermal breaks that reduce heat and cold transfer from front to back of the sections. 

Like many of the commercial garage door products available from The Overhead Door Company, the [Sectional Thermacore AP 850 series](https://www.overhead-doors.com/overhead-door-blog/thermacore-ap-door-850-series) is available in several basic colors, so you can choose the right one for your particular outdoor color scheme. Additional features are available on this door including high-cycle springs, high-usage components, electric commercial operators, and other options. This level of design flexibility is one of the most popular features of the Thermacore doors.
