The Best Underfloor Insulation for Timber Floors

EXPOL underfloor insulation is not only light weight allowing for an easy install, but it is also rigid. This means it won’t sag over time, like other products do. With a 50 year product guarantee, you will have the peace of mind that your floors will stay well insulated over the years to come.


All Expol panels are concertina cut on both sides to allow for a compression of up to 20mm for ease of installation, and to ensure a snug fit between the joists.


  • EXPOL UNDERFLOOR R1.4 (in 360, 410, 470, 560 to fit existing joist widths)
