All panels are con-cer-tina cut on both sides to allow for compression of up to 20mm for ease of installation, and to ensure a snug fit between joists. This snug fit is essential in improving insulations effectiveness and reducing draughts.

Expol has an R-value of 1.4, which exceeds current recommended r-values for underfloor insulations. The flame retardant polystyrene panels are 1.2 metres long and 55mm thick. They are produced in four standard widths to fit between most standard joists.

Expol is DIY friendly, and can easily be installed by a DIY enthusiast.

Good insulation can pay for itself in energy savings. Expol comes with a 50 year warranty and guaranteed R-values
