MAHON insulated rolling doors combine the weathertight construction and rugged features of ALL-SEAL rolling doors with the advantages of polyurethane insulation. Where the prevention of heat loss is a major consideration the MAHON INSUL-SEAL door is a truly effective insulated rolling door with many advantages. Each door is a custom fit for any opening condition and will help control energy costs year after year. The end result is a finished appearance from inside and outside. Perimeter weather seals insure a highly efficient closure. Each slat is made up of the Mahon #5 slat and a steel panel which encloses the polyisocynurate insulation, thus eliminating the insulation voids inherent with “foamed in place” type insulation. The resulting total polyisocynurate coverage permits full utilization of the materials R factor of 7.90.	Hood Weather Baffle is standard with the All-Seal Weather Door; lintel baffles also available. Optional fascias usually required for applications to metal buildings.
