Polyisocyanurate

What is Polyisocyanurate (PIR)?

Polyisocyanurate is an evolution of polyurethane. It is stronger and has greater thermal resistance. In fact, PIR offers the highest R-value of any material per thickness. Combined with a foil facing, the joins between PIR boards can be taped after other services have been installed, giving a tidy solution for visible areas such as car park under soffit.

• Under soffit/car park insulation
• Cavity walls
• Flooring
• Some roof applications.

Composite Global supply 2 varieties of PIR, which are available in a variety of thicknesses and finishes.

• Thermasheath-3: For highest performance
• Eco-Max: Contains renewable content for extra sustainable credential.

High Thermal Performance

Thermaseath-3 PIR is a superior insulation. When covered in one of a variety of facings, PIR offers very high thermal resistance for the thickness of the product.

Healthy and Clean

PIR is moisture repellent, resisting mould and helping to retain the insulative properties throughout the life of the product.

PIR carries a BCA Group Classification 1 for fire safety.

Greener

The polyisocyanurate foam manufacturing process is HCFC/CFC free, giving PIR an ODP-zero rating. Composite Global can also supply Eco-Max, which in addition to being ODP-zero, it is made from at least 8% renewable material, further boosting the environmental credentials of the building.
