Thermacore® Insulated Sectional Steel Doors

The Overhead Door Company’s Thermacore® technology has become the garage door industry standard for insulated sectional doors. Thermacore® employs polyurethane foam to fill doors resulting in excellent thermal properties; especially useful for Michiana’s cold winters and hot summers.


  • Continuous foamed in place polyurethane insulation and roll-formed, hot dipped galvanized steel construction provides superior thermal efficiency, exceptional strength-to-weight ratio and proven durability.
  • Dual thermal break and joint seal between internal and external skins minimize air infiltration and provides the highest door system thermal efficiency in the industry.
  • Specially designed track and heavy-duty fixtures ensure a tight and reliable fit.
  • Two coats of baked-on polyester paint provide a durable finish.
