Cavity wall insulation is absolutely essential to all buildings, preventing heat loss and potential draughts penetrating through the cavity. At MacBlair, our range of Unilin partial fill cavity wall insulation is tongue and grooved, ensuring insulation continuity and minimising the protentional of thermal bridging. We also keep Unilin full fill insulation, which achieves passive U-values as low as 0.12 W/m2K!
