  • Our new ThermalBuilt R-10® door provides our valued customers with a R-10 thermal value (U-factor .10). These doors have been developed with the help of North Carolina State University.

          These doors are "green" products:

  • the polyisocyanurate foam contains recycled content
  • no CFCs
  • zero ozone depletion potential
  • virtually no global warming potential
  • the door skins are either natural wood or Eucalyptus oil based (vs. petroleum based)
