Terra Lana underfloor insulation is a wool/ polyester laminate specifically designed for the underfloor insulation of new and existing suspended floors.
The blanket segments are constructed with a thick top layer of wool and the bottom surface as a thinner layer of melt bonded polyester which gives rigidity to the segment, preventing sagging between joists and a stiffer friction fit.
Terra Lana natural wool insulation was developed and tested by the Wool Research Organisation of New Zealand (WRONZ,now AgResearch).
