Sectional Steel Doors

​The Thermospan® Model 150 features polyurethane insulation and is an excellent value when thermal efficiency is important, but strength, rigidity and durability cannot be compromised.

  • Polyurethane insulation, R-value* = 14.16
  • Max width: 26’2”
  • 1-3/8” section thickness
  • Patented, roll-formed integral struts for rigidity
  • Stucco embossed exterior with pinstripes available in white, tan, gray and brown; also available with TruChoice™ Color System
