Excellent Fireproof and Moisture-Proof Performance of Phenolic Foam Insulation Board

In the developing field of energy-saving and fireproof buildings, phenolic foam insulation board with high-performance heat insulation is rapidly becoming the preferred material for modern architects and engineers due to its excellent fire and moisture resistance

In the ever-evolving world of energy-efficient and fire-safe construction, HENGLICAI is rapidly becoming the material of choice for modern architects and engineers. Known for its outstanding fireproof and moisture-resistant properties, this high-performance insulation solution is setting a new standard in the global building industry.

Manufactured from rigid thermosetting phenolic resin, phenolic foam insulation board exhibits exceptional fire resistance, earning it a Class A or B1 fire rating in many international safety tests. Unlike traditional insulation materials, it produces very low smoke and minimal toxic emissions when exposed to high temperatures, making it an ideal choice for residential towers, commercial facilities, and public infrastructure projects where fire safety is critical.

In addition to fire protection, phenolic foam boasts superior moisture-proof capabilities. Its closed-cell structure—with over 95% of cells fully sealed—prevents water absorption and vapor penetration. This ensures long-term thermal stability and prevents issues such as mold growth, degradation, and energy loss due to damp insulation layers.

Thanks to its low thermal conductivity (approximately 0.017–0.024W/m·K), phenolic foam insulation board also offers excellent insulation performance with thinner profiles. This makes it highly suitable for applications such as external wall insulation (ETICS), roofing systems, HVAC ducting, cold storage, and industrial piping.

As global construction moves toward higher energy-efficiency standards and stricter fire regulations, phenolic foam insulation board stands out as a smart, sustainable, and safe insulation solution. Its growing popularity in Europe, Asia, and the Middle East reflects a broader shift toward performance-driven materials that do not compromise on safety.

For contractors, developers, and specifiers seeking a reliable and certified insulation product, phenolic foam insulation board delivers unmatched protection—both inside and out.
