Platinum Board has the same physical characteristics as ThermaSlab, with the addition of graphite to the raw material. It is a superior material, offering supreme R values for maximum insulation for floors, walls, and roofs. Platinum Board comes in a range of sizes and thicknesses suitable for all applications.

  • Masonry wall
    insulation
  • Concrete floor
    insulation
  • Skillion roof insulation
  • Cladding insulation
EXPOL provides high performance, solid insulation solutions for insulating both interior and exterior masonry walls. EXPOL Platinum Board is ideal for insulating the interior of a masonry wall. It provides high R values for its relative thickness. See Expol-X for an exterior solution or view our solution guide here.

Masonry Wall Insulation

EXPOL Platinum Board is a premium product for insulating under a concrete floor. Ideally suited for where insulation thickness may be restricted and high R values are required.
For other products suitable for under concrete insulation, refer to our solution guide here.

Concrete Floor Insulation

EXPOL provides solid insulation solutions to solve the difficulties in achieving high R values in narrow roof spaces. EXPOL Platinum board for skillion roofs are panels cut to suit a variety of purlin / rafter spacings. For more information refer to our product solution guide here.

Skillion Roof Insulation

EXPOL supplies both EPS and XPS sheets for EIFS cladding systems. EXPOL's EPS sheets have been tested and satisfy all the requirements necessary to be listed as a preferred provider for all EIFS systems.
