When openings are made into fire-rated air ducts, their insulation is usually damaged, putting the entire ventilation system and the building at risk. The METU FR-S access doors provide a convenient access into the fire-rated air-ducts as often as required without loosing the fire-rated characteristics of the ventilation system.
