65mm Isover CWS 32 batt is a dense glass wool insulation product, providing high thermal performance in masonry cavity wall insulation, applicable in various type of buildings including domestic, commercial, industrial, health, retail, education. The products density allows it to have extremely low U values of even up to 0.23 W/mK, thus conforming to values prescribed by the applicable Building Regulations and providing substantial acoustic insulation by minimizing flanking sound transmission through the cavity. Resilient and flexible insulation batts are made to fit between standard wall tie spacing, able to withstand moisture exposure in storage, during transportation and installation.
