SLABX200 is EXPOL’s new generation high performance Expanded Polystyrene Board specifically designed to deliver high compressive strength and improve insulation under concrete slabs.

It delivers an uncompromised compressive strength of 200kPa @ 10% deformation and exceptional Insulation Values. Specifically engineered for residential and commercial projects, its high performance gives engineers and specifiers peace of mind while increasing the thermal performance of a building.

SLABX200’s durable nature means it will not degrade over time keeping its integrity for the life of the structure.

What is R-Value?

An R-Value is a rating which measures how well insulation can resist heat flow. ‘R’ stands for thermal resistance.

  • R-Value level depends on a number of things such as the type
    of material, its density and thickness.
  • Higher R-Value = Better insulation.

What size board is EXPOL SLABX200 available in?

EXPOL SLABX200 is available in 2400 x 1200 sheet sizes.

Does SLABX200 come in a range of different thicknesses?

Yes. SLABX200 is available in 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 100mm, 110mm, 120mm, 150mm, 200mm.
