Inspection hatch for installation in Siniat plasterboard ceilings. It consists of two frames made of aluminum angle bar: external (frame) and internal, which constitute the structural frame of the damper leaf. The damper is filled with Nida Ogień + plasterboards, 2 x 12.5 mm thick. The damper has an intumescent fire seal about 1 mm thick, glued to the leaf along the entire circumference of the damper. Single-leaf Promat inspection hatches are used in solid ceilings (reinforced concrete or prefabricated) and suspended ceilings with a fire resistance class not lower than the fire resistance of the inspection hatches. They allow you to carry out the necessary inspections, inspection and maintenance of the system in installations mounted above the fireproof ceiling.
