DB11/T 941-2021 "Technical Specifications for Inorganic Fiber Lame Plating Engineering" Abstract DB11/T 941-2021 is a local standard in Beijing, which stipulates the design, construction and mass acceptance requirements for inorganic fiber lame plating engineering. Inorganic fiber lame plating is a new type of thermal insulation, fire protection and sound absorption technology, which is suitable for building walls, ceilings and curtain walls and other parts. The standard clarifies the structure of inorganic fiber lame plating system, including base layer, interface layer, lame plating layer and protective layer, and proposes performance requirements, construction process and mass acceptance standards. This revision adds energy-saving design indicators, vapor barrier layer requirements and sound absorption and sound insulation performance indicators, aiming to standardize the construction process, ensure the mass of the project, and promote the wide application of inorganic fiber lame plating technology in the construction field.
