While providing energy efficiency, Cookson Insulated Doors also offer aesthetic appeal with a finished appearance inside and out. Our exclusive interlocking slat design allows for many combinations of gauges. While a 22 gauge exterior slat with a 22 gauge interior slat is standard, 20 gauge and 18 gauge exterior slats are also available.


  • Heavy duty vinyl extrusions snap into the guides to reduce air and dust infiltration and to weatherstrip the door jambs
  • Air seepage around the hood is minimized by a water resistant hood baffle that maintains flexibility in cold temperatures
  • Exclusive interlocking slats provide energy efficiency and a finished appearance inside and out
  • Solid insulation is inserted between galvanized steel slats to ensure consistent density and complete insulating coverage
  • The bottom of the door is sealed by a flexible, solid foam astragal
