Fire-Resistant PVC Foam Core Sheet for Building Facade Cladding and Interior Wall Partition Systems

This product typically achieves a Class B1 rating (combustible but difficult to ignite) according to the Chinese standard GB 8624-2012, or higher. Some products can meet international certifications such as UL94 V-0. Its specialized formulation and additives effectively inhibit flame spread and reduce smoke production, meeting fire safety requirements for building facades and interior partitions.

Compared to traditional metal or solid panels, fire-resistant PVC foam core sheet offers high strength-to-weight ratio, excellent thermal and acoustic insulation, and strong weather/corrosion resistance. Its sandwich structure reduces building load, improves energy efficiency, and allows for easy cutting and installation. It is ideal for modern architectural facades and fast-track assembly.

Yes. PVC foam core sheet has a closed-cell structure, making it highly waterproof and moisture-resistant. It does not absorb water, swell, or promote mold growth. When combined with proper waterproof sealing, it is fully suitable for interior partition systems in humid areas like restrooms and kitchens.

Installation typically combines specialized structural adhesives with mechanical fastening (such as screws with battens). The substrate must be flat, solid, and free of oil or contaminants. For facade cladding, drainage/ventilation layers and wind/earthquake-resistant detailing should be included per code. For interior partitions, it can be attached directly to steel studs or solid wall substrates.

Modern fire-resistant PVC foam core sheets often use environmentally friendly formulations free of CFCs/HCFCs, and some products are recyclable. Their durability and energy-saving characteristics help reduce the carbon footprint over the building's lifecycle. We recommend selecting products that comply with green building material standards or hold certifications such as EPD.
