    What is Cavity Wall Insulation?

    Outer Cavity Wall Insulation

    A cavity wall is made up of two layers/walls with a small gap in between, known as the cavity. Most traditional walls built with brick, stone, timber or some other material will have cavity. Same applies to most internal walls where there will be some cavity between the two faces of the wall.

    Cellulose insulation is blown into the cavity, under pressure through a predetermined pattern of drilled holes ensuring total fill of the cavity. When completed, the holes are filled and covered.

    Once installed properly, Cellulose Cavity Wall Insulation will provide

    • Thermal Efficiency
    • Sound Proofing
    • Fire Resistance

    and should last the lifetime of your house.
