Choose Rigid Foam Board Roof Insulation by Foamex

PurlinK is a specially designed rigid foam board roof insulation solution by Foamex, a recognised leader in polystyrene innovation in Australia. Based in Victoria, the quality-endorsed company has been in the business for three decades and counting. Foamex has established a strong presence across the country for their carefully curated catalogue, delivered with world-class service.

Rigid Foam Board Roof Insulation
Foamex specialises in the design, manufacture and distribution of both expanded and extruded polystyrene. The former is widely used for its cost-effective thermal performance, and versatility for a wide range of applications, such as architectural profiles, cold storage, protective packaging, 3D signage, theatre props and other decorative fixtures. On the other hand, extruded polystyrene is highly recommended for high-performance insulation, coupled with outstanding compressive strength and dimensional stability.

During manufacture, the production team at Foamex combines solid beads of polystyrene resin with additives in an extruder. The mixture undergoes a melting process in a viscous liquid before a blowing agent is injected to expand the volume of the resin beads. Under controlled heat and pressure, the mixture is forced through a die. The end-product is lightweight, yet high-quality extruded polystyrene, ready for cutting and installation.

PurlinK harnesses the sought-after properties of extruded polystyrene to result in a rigid foam board roof insulation material. The insulated panels are called roof spacers, specially designed to help reduce the heat escaping from metal deck roofing applications. The resulting thermal break allows PurlinK to recover the nominal thickness of the insulation system. This setup maintains the insulation profile to increase thermal resistance or R-values, and optimise thermal performance.
