The standard aluminum silicate fireproof wrapping can meet the fire resistance limit requirements (integrity and insulation) of 0.5h, 1.0h, and 2.0h, meeting the design requirements of building smoke control systems. The heat that can isolate fire smoke is transferred through the pipe wall, eliminating smoke and heat during a fire, ensuring personnel evacuation and firefighting rescue. This lightweight, ultra-thin, and compact structural system is a breakthrough innovative solution that replaces the traditional rigid fire-resistant coating system for air ducts (fireproof board+rock wool). $r $n $r $n Product Composition $r $n $r $n Core Materials: Aluminum silicate, alkaline earth calcium silicate magnesium fiber. $r $n $r $n Surface packaging: Aluminum foil
