Composite Global Solutions explains why PIR rigid board insulation is one of the best insulation products on the market.

As one of Australia’s fastest growing insulation suppliers, the company seeks to clear the confusion among customers about insulation solutions that best suit their needs. One of the most popular among all of their insulation categories, Polyisocyanurate (PIR) rigid board insulation is evolved from polyurethane and is stronger, has greater thermal resistance and offers one of the highest R-values per thickness of any insulation material on the market today.

5 reasons why PIR rigid board insulation is the best

Thermal Performance

Composite Global Solutions’ PIR insulation boasts a thermal conductivity rating of 0.022 W/m°K, which exceeds the typical 0.023 W/m°K thermal performance of PIR insulation available in the market.

Fire Performance

PIR insulation is a thermoset material - when exposed to fire, it will not melt and create a hazard for firefighters or exiting occupants. Composite Global Solutions’ PIR TS3 product has a Class 1 BCA Group Classification (AS/NZS 3837 – 1998).


PIR insulation is generally cost effective, but Composite Global Solutions’ PIR product is significantly cheaper than the competition as the company works with suppliers to pass on any cost savings directly to the customers.

Multiple Applications

PIR rigid board insulation is a versatile product and can be used in a wide variety of situations including, but not limited to, under soffit, car park, stud/masonry/cavity wall, re-siding, vaulted ceilings, attics, crawl spaces, and some roofing applications.

Moisture and Compression Resistance

Being a closed cell material, PIR insulation does not absorb water, ensuring the thermal and structural performance of the insulation is maintained over time. This same closed cell structure enables PIR rigid insulation boards to have excellent compressive strength, allowing their use in a wide variety of applications unsuitable for other insulation products.
