Expol Underfloor Insulation

Expol is polystyrene boards with a special concertina cut on both sides to allow for up to 20mm compression to make installation easy.  Expol will fit snugly between the joists without the need for fixings – in most cases, the boards will self-support.
This product has been specifically designed for insulating between the joists of timber floor homes and buildings and can be fitted to new homes or retrofit.
Expol is perfect for homes with exposed timber floors, keeping draughts and moisture out, and the heat in.  It is made from flame-retardant polystyrene, is non-allergenic and non-irritant.  It has excellent thermal properties (R1.4) and will increase the insulation rating of your home, reducing costly energy bills by up to 12%.
The boards are 1.2m long and 55mm thick and come in four standard widths of 560mm, 470mm, 410mm, and 360mm to fit between most joists.  They comply with the Australian and New Zealand Standard for insulation and Australian Standard for manufacture.
Expol Wire Guard is available for wrapping around PVC cables before installing insulation.  Non-corrosive nylon fixings with stainless steel nails should be used only where panels are loose or where the floors are subject to wind.

Expol Benefits

One of the biggest benefits of EXPOL underfloor insulation panels is that they are rigid, which means they do not sag. Soft, pliable insulation material such as glass wool or polyester has the potential to sag after many years.

The lightweight, rigid design of EXPOL underfloor means:

  • Underfloor insulation stays in place which ensures a consistent thermal performance as heat can’t escape through new cracks.
  • No need to replace in the years to come and incur expensive stripping and re-installation costs.
  • Moisture and vermin are unable to enter through newly formed gaps.
    Expol is also fire-retardant, water resistant, and non-allergenic.
