PIR Foam Boards

Pir foam boards are high-grade polyisocyanurate rigid insulation manufactured at KURTIN's Zhejiang factory with continuous automated foaming lines. Tuned proprietary chemical formula upgrades fire resistance and low thermal performance, outperforming traditional EPS and regular PUR foam for cold storage, roofing and building envelope projects. Thanks to stable performance from -50℃ up to 150℃ long-running temperature scope, pir foam boards have become the preferred thermal solution for global cold-chain contractors and green building developers.

Closed-cell proportion exceeds 90% to block inner air convection, keeping thermal conductivity below 0.024W/(m·K) for outstanding energy conservation. Available B1/B2 flame retardant grades hold oxygen indexes of 30% and 26% separately; the foam forms dense carbon char while burning to limit flame spread and reduce toxic smoke emission, complying with EU construction fire codes. Compressive strength above 150kPa avoids indentation under floor screed and rooftop dead load, while customizable square, shiplap and tongue-and-groove edges minimize thermal bridging during field splicing. Buyers can pick skinless, aluminum foil or fiberglass cement facings to match different bonding and vapor barrier requirements.
