PU PIR Insulated Wall Sandwich Panels with Fire Resistance Panels

Product introduction

PU (polyurethane) wall sandwich panels are fire-resistant options that combine a PU foam core with metal facings to offer excellent thermal insulation and structural properties. While standard PU panels have limited fire resistance, panels with a PIR (polyisocyanurate) core offer improved fire performance by slowing flame spread and reducing smoke emission. These panels are used for both exterior and interior walls in various applications, including industrial buildings, clean rooms, and warehouses, due to their easy installation, durability, and versatility.
