Product Overview
PIR Cavity Wall Insulation Board is a high-efficiency thermal insulation material specifically designed for cavity spaces in building envelopes. Utilizing polyisocyanurate (PIR) as the core material and manufactured through specialized processes, this product perfectly integrates into wall cavities to form a continuous, thermal bridge-free insulation layer. Its unique closed-cell structure effectively blocks heat transfer and prevents energy loss caused by air convection within cavities, making it an ideal choice for building energy conservation and consumption reduction.

Key Advantages

  • Precise Cavity Fit
    Available in multiple thickness specifications to accurately match various wall cavity widths. The tongue-and-groove design ensures a complete sealed insulation layer after installation, effectively eliminating thermal bridging.

  • Excellent Thermal Performance
    With ultra-low thermal conductivity (≤0.022 W/(m·K)), it significantly enhances the wall's overall insulation effect, effectively reducing building heating and cooling energy consumption, and assisting in achieving passive building standards.

  • Long-lasting Moisture Resistance
    The high closed-cell content (≥96%) structure effectively resists moisture intrusion in cavities, remaining non-absorbent and non-deformable during long-term use, ensuring lasting insulation performance.

  • Safe and Environmentally Reliable
    Meets B1 flame-retardant standard with excellent fire performance and does not release harmful substances, providing dual safety protection for buildings.
