Hebei releases unified technical measures for external thermal insulation of civil buildings
In order to eliminate the safety hazards of the external thermal insulation project of civil buildings and improve the quality of the external thermal insulation project of civil buildings in Hebei Province, on May 15th, the Department of Housing and Urban-Rural Development of Hebei Province issued the "Unified Technical Measures for the External Thermal Insulation Projects of Civil Buildings in Hebei Province". The external wall thermal insulation technology and thermal insulation products to be promoted and the restricted external wall thermal insulation technology and products are clarified. The unified technical measures will be implemented from July 1, 2021.
In terms of external wall insulation technology to be promoted, it mainly promotes the use of cast-in-place concrete built-in thermal insulation system, steel wire grid composite board sprayed mortar exterior wall thermal insulation system, large mold built-in cast-in-place concrete composite insulation board system, large mold built-in cast-in-situ concrete insulation system The four technologies of the board system, and make clear requirements for their technical characteristics, technical measures, implementation standards, scope of application and basis.
In terms of popularized insulation products, it mainly promotes the use of A2 and B1 insulation materials, and makes clear requirements for their technical characteristics, technical requirements, implementation standards and scope of application.
Regarding the restricted use of external wall insulation technology and products, the construction site adopts cement or anchor bolts and a combination of thin plaster external wall external insulation systems, and it is prohibited to use the external wall of the external wall of the new, rebuilt, or expanded civil construction project. The main thermal insulation system is designed and used (except for masonry structures), and can be used in new, rebuilt, and expanded civil building masonry structure projects, existing buildings, and old community renovation projects. Combustion performance is B2 grade materials and extruded polystyrene foam panels for thermal insulation, and it is forbidden to design and use the outer wall of the main thermal insulation system on the outer wall of the newly built, rebuilt, and expanded civil construction. Extruded polystyrene foam panels for heat insulation produced from recycled materials can be used in roofing and ground engineering.
According to requirements, before July 1, 2021, projects that have not yet obtained construction permits should be strictly implemented in accordance with this regulation; projects under construction that have obtained construction permits, and if this regulation has not been implemented, the construction quality of the construction unit should be compacted The primary responsibility for safety is to strengthen the daily inspections, special inspections and hidden danger investigations of the external insulation engineering of the building's external walls. The hidden safety hazards found should be dealt with in a timely manner, and the fire safety education and system of the personnel in the building shall be implemented to ensure the safety and reliability of the project.
