PIR insulation board is popular among all insulation categories. It is one of the most versatile, thermally efficient and readily accessible insulation materials available today. A step up from polyurethane, the PIR board has one of the highest R-values per thickness compared to any other insulation material in the market.
*Highly durable: PIR insulation is highly durable and lasts longer.
*Lightweight: It is easy to handle and transport, making installation much faster. Their small weight makes them ideal for modern construction technologies and lightweight supporting structures.
*Versatile: Used for a variety of industrial insulation purposes.
*Moisture resistant: PIR insulation boards do not absorb moisture and thus, retain their weight and insulation properties.
*Resistant: PIR insulation boards retain their original shape even after much wear and tear.

It is a kind of ideal organic thermal insulation material applied at low temperatures, resulting in its low thermal conductivity, lightweight, anti-vibration, and compatibility. It is widely used as insulation in oil refinery, chemical, ethylene, and fertilizer industries, as well as refrigeration house and LNG systems.
*PIR shall be handled gently, avoiding rolling, collision and heavy pressure during moving.
*When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band.
*Cut it with saw during application.
*Store in a dry, lightproof, shady, and ventilated place, keep away from the heat sources and protect from sun exposure.
*Inner Packing: Polythene bags Outer Packing: Cartons.
