Scope

Scope: This standard specifies the construction of external thermal insulation walls for non-curtain wall buildings using AEPS (Agglomerated Expanded Polystyrene) as the material, including the installation of anchors and rigid brackets, as well as general construction nodes. This standard applies to the design of external thermal insulation projects for new, renovated, and expanded civil buildings in Tianjin City, which use reinforced concrete or masonry as the base wall. It also applies to the design of energy-saving renovations for civil buildings and external thermal insulation projects for industrial buildings. This standard is suitable for areas with a seismic crack resistance of less than or equal to 8 degrees. Main technical content: AEPS (Agglomerated Expanded Polystyrene) is a foam board material made from flame-retardant polystyrene particles as the main raw material. It is treated with a fire-resistant coating on the surface, and has excellent fire-resistant and thermal insulation performance, a combustion grade of A2, a thermal conductivity of ≤0.045W/(m2·K), stable physical properties, and good resistance to external factors. It can be used for external thermal insulation of buildings (without the need for additional fire-resistant strips or protective layers) and roof insulation, etc.
