    R1.5 Polyester underfloor insulation is recycled a product and the most robust insulation on the market, environmentally friendly polyester retains it's loft better than any other insulation which means it can give it's full R value for more years than glass wool products.

    Polyester doesn't absorb moisture so perfect to stop rising damp and underfloor moisture damage, it won't get heavy with moisture and fall out due to weight.

    Doesn't carry odours.

    No special clothing needed to install but a dust mask is recommended, perfect for DIY as easy to handle as it comes in small rolls in the pack.

    Very Important to measure gap between floor joists to get the correct width(size) roles.
