PIR insulation boards are rigid foam panels made from polyisocyanurate, offering excellent thermal performance, moisture resistance, and durability. Commonly used in walls, floors, and roofs, PIR boards feature low-emissivity foil facings that enhance insulation and act as vapor barriers. With a low thermal conductivity (as low as 0.022 W/m·K), they are ideal for modern construction standards requiring space-efficient and energy-efficient solutions.
