Polyisocyanurate (PIR) Foam

Polyisocyanurate (PIR) is a rigid, high-strength thermoset foam core designed to deliver exceptional insulation. Unlike standard foams that melt under fire conditions, PIR forms a protective char layer when exposed to flames, improving its fire resistance and structural performance. PIR panels are ideally suited to projects that demand superior thermal efficiency, FM Approved certification, and compliance with cyclonic region requirements. Bondor’s MetecnoPIR range features versatile solutions including MetecnoPanel®, MetecnoInspire®, MetecnoSpan®, and EconoClad® – each designed to combine energy efficiency with strength, durability, and design flexibility.
