Terra Lana Wool Blend Thermal Underfloor Insulation

Our underfloor insulation is specially designed with a thick top wool layer with a semi-rigid polyester base layer to give rigidity and prevent wind wash. Designed to be exposed and retrofit installed from the underside of a timber subfloor, our standard wall and ceiling insulation can be used when enclosing the underfloor and installing from above. Underfloor insulation can be stapled or friction fit between joists depending on spacings. Lengths can be ripped by hand or cut for irregular spaces. Supplied in standard or custom widths. 

*Allow approximately 40-60mm wider than the joist inside measurement for retrofitting and 10mm wider for installing from above.
