Import A1 Class Non-Combustibility Mineral Wool Board — Buy in wholesale FOB from Supplier in China

A1 Class Non-combustibility Mineral Wool Board from Tianjin Haimen Building Materials Co., Ltd is a stone wool insulation panel rated A1 under EN 13501-1, meaning it does not contribute to fire development or spread. The board provides both thermal and acoustic insulation, with a lightweight structure that simplifies handling and installation on site. It is manufactured in Tianjin, China, and is positioned for construction, industrial, and fire-protection system applications where non-combustibility is mandated.

Mineral wool of this grade is typically produced from basalt or diabase rock and slag, melted at approximately 1,400 °C and fibre-spun with a phenolic or bio-based binder. The A1 rating requires negligible organic content, so combustion heat release is minimal. Standard industry dimensions range from 600 mm x 1,200 mm to larger modular sizes, with thicknesses from 25 mm to 150 mm; density for roofing or wall applications commonly falls between 80 kg/m³ and 140 kg/m³. Thermal conductivity at mean temperature is typically 0.035 W/(m·K) to 0.040 W/(m·K). Tianjin Haimen does not list exact dimensional or thermal values, so buyers should request the product data sheet.

Typical applications include curtain wall cavity barriers, roof deck insulation, fire-protection encasement for steel and ductwork, and acoustic ceiling baffles. Buyers are normally contractors, M&E consultants, and distributors serving commercial and infrastructure projects. The listing mentions flexible minimum order quantities and customisable packaging, but exact figures are not provided. Certifications and standards compliance are referenced without naming specific certificates or test houses; buyers must verify these directly with the supplier.

Tianjin Haimen Building Materials Co., Ltd is located at No. 2352-600 Tanghan Road, Tanggu Marine Science And Technology Park, Tianjin Binhai High-Tech Zone, Tianjin 300451, China. The supplier holds a harbor trust tier. The response rate is recorded at 0.00% with zero average response hours, which suggests limited platform engagement; buyers should initiate contact early and consider alternate channels if no reply is received within a reasonable timeframe.

The company positions itself as a manufacturer of building materials with a focus on fire-resistant insulation. No information is provided about factory floor area, production capacity, year of establishment, export history, or client references. The source description contains promotional phrasing that attributes manufacturing to the platform rather than the supplier, which should be disregarded; buyers must verify that Tianjin Haimen is the actual producer and request factory audit or video verification.
