Expol underfloor insulation is a polystyrene insulation board specifically designed to insulate between the timber floor joists of homes and buildings.

Easy to install

Expol is easy to DIY, even in a confined space. Each board is 1.2 meters long and has concertina cut edges that simply hold the board in place without any need to drill or screw into the studs. Expol comes in 4 standard widths to fit easily between most joist spans, but can be cut down to fit irregular spans and shapes.

High R-values

One sheet of Expol has an R value of R1.4, well above the minimum recommended R-value for timber floor insulation. Insulation is vital in maintaining energy efficiency, and an uninsulated floor allows heat to easily escape from your home. An R-value of 2.8 can be easily achieved by simply installing two sheets instead of one. This is especially useful in areas with extreme cold, such as alpine and high snow areas.

Eliminate draughts

Expol’s concertina-cut sides push against the wooden joists, holding itself in place and eliminating draughts by sealing up the floor.

New or old homes

Expol can be installed in new homes to meet insulation requirements or existing homes to improve comfort and energy efficiency.

50-year guarantee

This product has a 50-year guarantee, providing you and your family with quality insulation for years to come.
