IDEAL USES

Cladding Insulation

EXPOL Platinum Board is a premium polystyrene solution for exterior insulation finishing systems (EIFS) that achieves superior R-values relative to its thickness.  The rigid foam composition of EXPOL Platinum Board ensures it will not slump or sag.  It is available in full sheets and is easy to cut to a specific size. 

Other Applications

EXPOL Platinum Board is a lightweight expanded polystyrene (EPS) board that is easy to handle and easy to install. 

An inert product, EPS does not degrade over time meaning that thermal insulation performance is ensured for the life of the building.  At a thickness of 30mm, EXPOL Platinum Board delivers an R-value of .94. 

Compared to high density EPS, Platinum Board uses fewer raw materials during processing without reducing insulation performance.  This makes EXPOL Platinum Board one of the most eco-efficient choices for polystyrene insulation. 

The unique matrix structure of EXPOL Platinum Board gives exceptional rigidity and strength.  EXPOL Platinum Board has a well-regarded reputation as a reliable insulation product suitable for use in floors, walls and roofs. 

For cost effective cladding insulation, choose EXPOL ThermaSlab S. For applications where high water resistance and compressive strength is required, choose EXPOL-X.

FREQUENTLY ASKED QUESTIONS

Does EXPOL Platinum Board satisfy the requirements for a preferred provider of EIFS? 

Yes.  EXPOL’s EPS sheets have been tested and satisfy all the requirements necessary to be listed as a preferred supplier for all EIFS. 

How effective is EXPOL Platinum Board for thermal insulation? 

Is EXPOL Platinum Board durable? 

The unique matrix structure of expanded polystyrene (EPS) creates block rigidity and compressive strength making it an excellent choice for wall insulation.  An inert, rigid foam product, EPS holds its shape and does not deteriorate with age.  EPS does not settle over time, thus ensuring the R-value for the life of the building. 

Does EXPOL Platinum Board give off toxic fumes? 

In the event of a fire, the level of toxicity of EPS is no greater than timber.  EPS does not off-gas hydrogen cyanide or hydrogen chloride.  No CFCs or HCFCs are used in the manufacture of EXPOL Platinum Board. 

Is EXPOL Platinum Board water resistant? 

The closed cell construction of expanded polystyrene (EPS) ensures it resists any adverse effects of water.
