Product Description

Durable Polyurethane Insulation Board Non-Sandwich PIR Foam For Wall Roof Cold Storage

Product Description

PIR Insulation Board, also known as Polyisocyanurate Foam Board, is a high-performance rigid thermoset insulation material manufactured through a continuous lamination process. It features a modified isocyanurate molecular structure that delivers superior thermal stability and fire resistance compared to conventional polyurethane foam. The board typically consists of a rigid PIR foam core with a closed-cell content exceeding 95%, faced with glass fleece or aluminum foil on both sides for enhanced mechanical strength and durability. With an extremely low thermal conductivity of ≤0.022 W/(m·K), PIR Insulation Board offers outstanding energy efficiency while maintaining excellent dimensional stability and moisture resistance. It is widely used in building envelopes, cold storage facilities, and cryogenic pipeline insulation systems, achieving a B1 fire rating (self-extinguishing, low smoke) and providing reliable long-term insulation performance across a service temperature range of -196°C to +120°C.

PIR Pipe Shell is a pre-formed, rigid insulation product specifically designed for pipeline insulation in cryogenic and industrial applications. Manufactured from polyisocyanurate foam with a closed-cell content exceeding 95%, it provides exceptional thermal insulation efficiency with a thermal conductivity of ≤0.022 W/(m·K) at 25°C and approximately 0.017-0.019 W/(m·K) at -100°C. The pipe shell features a convenient two-half shell design, available with tongue-and-groove joints for secure fitting around pipes, and is supplied in 1000mm lengths with thickness options from 30mm to 150mm. With a service temperature range of -196°C to +120°C, B1 fire rating (self-extinguishing, low smoke), and low water vapor permeability, PIR Pipe Shell is the ideal choice for LNG terminals, petrochemical plants, and cryogenic pipeline systems where thermal efficiency and fire safety are critical.

Product Features

PIR insulation delivers outstanding thermal performance with a thermal conductivity as low as 0.022 W/(m·K) at 25°C. As temperatures drop, its insulating efficiency actually improves — reaching approximately 0.017-0.019 W/(m·K) at -100°C — making it particularly effective for cryogenic applications where thermal performance is critical.

With a closed-cell content exceeding 95%, PIR insulation minimizes water absorption and moisture ingress. The low water absorption rate (≤4.0% by volume) ensures consistent thermal performance throughout the service life, even in humid or wet environments. The extremely low water vapor permeability coefficient (≤5.8×10⁻⁹ g/(Pa·m·s)) further enhances moisture resistance, reducing the risk of corrosion beneath insulation.

PIR achieves an oxygen index of ≥30%, meeting B1 fire classification standards (difficult to ignite). When exposed to flame, the material forms a protective carbonized char layer and self-extinguishes once the ignition source is removed. It produces minimal smoke and does not contribute to fire spread, offering the highest level of fire safety available in organic insulation materials.

With a compressive strength of ≥220 kPa at 10% deformation, PIR insulation can withstand significant mechanical loads without damage or permanent deformation, making it suitable for load-bearing applications such as roof insulation and under-floor systems.

PIR insulation performs reliably across an exceptionally broad temperature spectrum from -196°C to +120°C, with short-term tolerance up to 150°C. This versatility allows a single material to serve both cryogenic cold insulation and moderate high-temperature applications.
