Raw Materials
Fiber-reinforced calcium silicate fireproof board, the material of Promat MASTERBOARD is off-white, free from asbestos or formaldehyde. It is a green and environmentally friendly material.
Product Benefits
Stable physical and chemical properties
Promat MASTERBOARD adopts advanced high-temperature and high-pressure steam curing technology in the production process. The product has a regularly arranged matrix crystal structure, and its physical and chemical properties are particularly stable. It will not deform or crack in an environment with drastic changes in humidity and temperature.
Strong fire resistance
Promat MASTERBOARD is a Class A non-combustible material. In the event of a fire, it will not burn or collapse. It can ensure that the fire smoke exhaust pipe continues to work for a long period of time, effectively preventing the dense smoke or toxic gas generated during the fire from spreading out. And prevent the fire from spreading along the air duct, ensure the safety of evacuation passages, smoke-proof stairwells and fire elevators, and win critical life time for personnel evacuation and fire rescue.
Convenient for installation
Promat MASTERBOARD is light in weight and easy to cut at the construction site. It is not limited by cross-section type and size. It is enough to fix the board on the keel skeleton by self-tapping screws. The whole process is dry construction and the installation speed is fast.
Applications Recommended
Passive fire-proof smoke exhaust duct
system dedicated to buildings, including: smoke exhaust (or combined with
ventilation) ducts in subway space, and pressurized air supply ducts in smoke-proof
stairwells or front rooms (located in areas with fire hazards) , All air ducts
passing through stairwells, front rooms or evacuation passages.
