Due to environmental pollution and other reasons, Beijing has added 5 types of construction materials that are prohibited from use

Beijing Housing and Urban-Rural Development Commission, Beijing Planning and Natural Resources Committee, and Beijing Urban Management Committee jointly released the “Beijing Municipal Materials Catalog (2018 Edition)”, This version adds 5 types of construction materials and equipment that are prohibited from use. The reasons for prohibiting their use mainly include environmental pollution, heavy pollution in the production process, and waste of energy.

The 2018 catalog includes a total of 77 prohibited products in 13 categories. In the original 2014 version of the catalog, 12 prohibited and restricted products were no longer included in the 2018 version of the catalog due to expired standards and other reasons.

Among the five prohibited building materials and equipment added to the 2018 edition of the catalog, naphthalene-based water reducing agents are The reason for prohibition is that the production process causes heavy pollution, and the reason for prohibiting the use of thermal insulation mortar that is not mixed in an airtight manner at the construction site is that it pollutes the environment. Coatings and adhesives that do not meet the “Volatile Organic Compound Content Limit Standards for Construction Coatings and Adhesives” are prohibited from use because they contain organic pollutants and emit harmful gases during construction.

In addition, the energy efficiency label is Level 2 and below, and the nitrogen oxide emissions do not meet the “Gas Heating and Water Boilers” Wall-hung boilers for gas heating that meet Level 5 requirements are prohibited from use due to their low energy efficiency and waste of energy. Due to poor elasticity and easy cracking, the use of polyvinyl chloride sealing strips, heat insulation strips, and warm edge spacers is prohibited.

The construction materials and equipment included in the 2018 edition of the catalog for the first time will cease to be listed in the 2018 edition of the catalog starting from June 1, 2019 Designed in Beijing civil construction projects, its use in Beijing civil buildings will be prohibited from October 1, 2019.
