Description:

Cookson insulated doors are manufactured with a process that is used by no other insulated door manufacturer, Cookson doors keep thermal losses to an absolute minimum. Although most door manufacturers use foamed-in-place insulation, Cookson uses solid insulation of the highest quality available with a flame spread not greater than 25 and smoke generation less than 50. Complete coverage and consistent density are assured by a piece of insulation placed between galvanized steel slats. A flexible, solid foam astragal fits into the guides at the bottom of the door to assure a complete seal across the opening. Seepage of air around the hood is minimized by a waterproof hood baffle that resists tearing and cracking and maintains flexibility in winter. The Cookson insulation system also includes snap-on guide weatherstripping made of heavy duty vinyl extrusions that are designed to reduce air infiltration and dust at any temperature. 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. Unique system for maximum insulation
