Typical PIR Insulation System Structure

PIR Shell: inner layer + middle layer (if necessary) + outer layer
Secondary Vapor Barrier: PAP aluminum foil
Main Vapor Barrier: mastic + fiberglass meshes + mastic
Metal Protective Layer: aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP
Sealant: HS-10-02, Foster 95-50, etc
Strapping Material: stainless steel tape, sub sensitive tape

Packing and Storage

Store in dry, lightproof, shady, and ventilated conditions
Keep away from heat sources and protect from sun exposure
Inner packaging: black polyethylene bags
Outer packaging: protective cartons

Cautions

Handle PIR materials gently - avoid rolling, collision, and heavy pressure during transport
For pipe and equipment insulation, fasten with glass fiber tape or steel band
Use saw for cutting during application
