    How does 100mm Celotex CW4000 Partial Fill Cavity Wall (6/pack) perform?

    The entire thickness range offers a low thermal conductivity (lambda value) of 0.022 W/mK, putting CW4000 among the best-performing widely-available insulation materials on the market.
    Celotex CW4000 will help to provide most of the thermal insulation performance in a cavity wall build up - but the overall heat loss from a building element depends on all of the materials used and the way they’re installed. Use our online and mobile U-value calculators to help you find the most efficient solution for your cavity wall.

    Product benefits
    The low emissivity aluminium foil facing on Celotex CW4000 helps to achieve lower U-values by increasing the thermal resistance of the air cavity it faces.
