Expol Insulation

Expol Underfloor Insulation

Expol underfloor insulation is the perfect choice for existing homes. Expol underfloor insulation will stop heat coming in over summer and escaping in winter.

Placed snugly between the floor joists, polystyrene insulation is a great flooring insulation choice for polished floors in bungalows and villas. Save around 12% on your heating bills. As polystyrene insulation consists mainly of stabilised air, Expol has excellent thermal properties. Expol insulation is safe to install, non-allergenic and contains a flame retardant. Its thermal performance is not affected by ageing, and it contains no CFCs. The polystyrene panels are designed to be self-supporting and nylon fixings are available for loose panels and for high wind areas.

Expol underfloor insulation is available in easy to handle polystyrene panels (R-Value = 1.4)
1200 x 560 x 60mm 
1200 x 470 x 60mm 
1200 x 410 x 60mm

Koolfoam Black Pearl
Ceiling and wall insulation 

As well as covering flooring insulation, Koolfoam also offers Black Pearl, a superior, rigid insulating material for ceilings, walls, concrete slabs and roof cavities. Black Pearl is a forward thinking solution for all applications where insulation is used in building and construction.

Black Pearl consists of expandable polystyrene (EPS) containing infrared absorbers. It is manufactured from Neopor, BASF’s innovative insulation solution.

It is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the resistance to the flow of heat, or R-value.

With an average R value of 1.3 at 40 mm thickness, Koolfoam Black Pearl is about 30% more thermally efficient than other standard EPS products; the ideal solution for thermal performance for N.Z conditions.

Koolfoam Black Pearl is used in the following applications in New Zealand:

  • Cavity roof insulation (ideal for skillion roofs) 100mm thick =R3.22
  • Cavity wall insulation (timber and steel frames) 70mm thick =R2.26
  • Underfloor insulation 60mm thick =R1.9
  • Under concrete slab insulation (superior compressive strength and High R vlaues)
  • Block wall insulation
  • Warm roof insulation
  • Pre-coated slab edge insulators
  • EIFS cladding systems
