New National Waterproof & Insulation Codes Take Effect | Jinsimai Empowers Engineering Material Upgrading with One-stop Building Material Solutions
New mandatory national codes, namely the General Code for Waterproofing of Building and Municipal Engineering and the Safety Technical Specification for Combustion Performance of Thermal Insulating Materials and Products Used in Buildings, have come into force. Coupled with China’s ongoing dual-carbon initiative, these regulations drive the domestic construction waterproofing and thermal insulation sectors toward standardized, eco-oriented industrial upgrading. Revised codes impose stricter criteria on the service life of waterproof materials as well as fire safety and environmental indicators for thermal insulation products, phasing out unqualified non-compliant goods from the market. As a result, project purchasers increasingly prioritize flame-retardant, low-carbon, long-lasting and eco-friendly construction materials. Nevertheless, most construction contractors struggle with two major challenges: selecting matched multi-category materials and sourcing products compliant with the latest statutory inspection standards. Rooted in Tianjin’s construction materials market, Tianjin Jinsimai Building Materials Technology Co., Ltd. has built a complete product portfolio grouped into four core segments: thermal insulation, waterproofing, steel structure components and color steel sandwich panels, delivering one-stop procurement solutions fully compliant with updated national construction codes.
Its thermal insulation series consists of five mainstream grades: rock wool, glass wool, NBR rubber foam, PU foam and phenolic foam. Grade A basalt rock wool features outstanding high-temperature fire resistance with thermal conductivity as low as 0.035 W/(m·K), ideal for external wall fire insulation and thermal wrapping of high-temperature industrial equipment. Formaldehyde-free centrifugal glass wool delivers superior sound absorption, widely applied for ventilation duct lining and mechanical room noise reduction. Closed-cell NBR rubber foam effectively prevents surface condensation and serves as a premium insulating option for HVAC pipelines. Low-thermal-conductivity polyurethane fits cold storage warehouses and high-spec passive houses, while low-smoke, non-toxic phenolic boards comply with stringent fire codes for shopping malls, hospitals and other public buildings. All thermal insulation products are manufactured in line with prevailing national energy-saving and fire protection specifications.
The waterproofing lineup covers four core products: TPO membrane, PVC waterproof sheet, HDPE geomembrane and SBS modified bitumen membrane. Heat-weldable and weather-resistant TPO is preferred for rooftop waterproofing of photovoltaic power plants and large industrial workshops. Corrosion-resistant PVC with robust welded seams is extensively adopted for underground basements and municipal tunnel projects. High impermeability HDPE geomembrane addresses rigorous anti-seepage requirements for landfills and aquaculture ponds, whereas cost-efficient SBS modified bitumen dominates aged residential roof renovation and conventional civil construction. Every waterproof product meets the statutory service life specified under the latest national waterproofing codes.
Backed by in-house processing workshops, Jinsimai provides custom steel component fabrication plus diversified color steel sandwich panels. Outfitted with CNC cutting and automatic welding production lines, the factory manufactures customized steel columns, beams and pipe trusses. Prefabricated sandwich panels filled with rock wool, PU or glass wool integrate fireproof and thermal insulating properties, enabling rapid on-site installation for wall and roof enclosure of prefabricated industrial plants.
Booming urban renewal, energy-saving retrofits of existing buildings and new-energy facility construction fuel robust market demand, prompting general contractors to opt for integrated bulk procurement. Going forward, Jinsimai will continuously upgrade product formulations to align with updated national standards and scale up R&D investment for eco-friendly building materials. Leveraging its full-range product layout, the company keeps supplying integrated solutions covering steel structures, thermal insulation and waterproofing for domestic and overseas municipal, civil and industrial projects, facilitating low-carbon and high-quality development across the construction industry.
