CavityTherm Flex is the perfect solution when insulating fair faced inner block walls or when block is laid flat resulting in an uneven surface to accept the insulation. The 25mm flexible fleece layer absorbs any variations due to block tolerances, providing a continuous unbroken bond between insulation layer and block. Passive level U-Values as low as 0.14 W/m²K with excellent thermal bridging detailing in cavities less than 150mm wide.
