Door Construction

construction of door
  1. Thermal break separates the inner and outer skins at the top and bottom so virtually no heat or cold is conducted through the section.
  2. Patented foamed-in-place technology bonds the polyurethane core to hot-dipped galvanized inner and outer skins, creating a door that is significantly more efficient than conventional insulated steel doors.
  3. Flush door embossed pinstriping (grooves) on the outer skin adds strength.
  4. Prepainted inner and outer skins are hot-dipped galvanized steel for added corrosion-resistance.
  5. Roll-formed integral struts add rigidity and strength.
  6. 18-gauge “wrap-around” end caps offer interior hinge attachment surface and exterior leg for proper seal against jamb.
  7. Joint seal prevents air infiltration and helps save energy.
