    Cavity Wall Insulation


    What is a cavity wall?

    A cavity wall refers to a type of construction where two layers of brick or blockwork are separated by a gap known as the cavity. This cavity helps prevent moisture penetration and improves insulation properties.

    Is my house suitable for cavity wall insulation?

    Most houses built after the 1920s have cavity walls and are suitable for insulation. However, certain factors such as the type of construction, cavity width, and condition of the walls may affect suitability. A professional survey can determine if your house is suitable.

    How is cavity wall insulation installed?

    Cavity wall insulation involves drilling small holes in the external walls and injecting insulation material, usually foam or mineral wool, into the cavity. The holes are then filled, leaving no visible signs of installation.

    I have vents at my property. What will your installers do with these?

    Vents are essential for ventilation purposes and must be kept clear. Installers will carefully work around vents, ensuring they remain unobstructed to maintain proper airflow.

    What about filling the holes?

    After the insulation material is injected into the cavity, the holes are filled with matching mortar or a suitable material to match the existing wall finish, leaving a neat and seamless appearance.

    What product do you install?

    The choice of insulation product depends on various factors such as budget, thermal performance requirements, and suitability for your property. Common options include mineral wool, expanded polystyrene beads, and injected foam.

    I live in a listed building, can I still have cavity wall insulation?

    isted buildings often have restrictions on modifications, including cavity wall insulation. However, it may be possible to insulate without causing harm, depending on the specific regulations and the expertise of an experienced professional. Seek advice from conservation officers or specialists.

    Does cavity wall insulation cause damp?

    When installed correctly, cavity wall insulation should not cause damp. However, poor installation or inappropriate materials can lead to issues. It is crucial to choose experienced installers and ensure they follow industry guidelines to minimise the risk of dampness.

    How long does it take to install cavity wall insulation?

    The installation time for cavity wall insulation typically takes around 2-4 hours. For a standard semi-detached property, it usually takes about 3-4 hours. The exact duration may vary depending on the size of the property and any specific requirements. It's always recommended to consult with a professional insulation service provider for a more accurate timeframe based on your specific situation.

    I have condensation on my walls. Can cavity wall insulation stop this?

    Cavity wall insulation can help reduce condensation by improving the thermal efficiency of your walls. However, it's important to identify the underlying causes of condensation, such as poor ventilation or lifestyle factors, and address them alongside insulation installation.

    Will installing cavity wall insulation make a mess?

    During the installation, there may be some minor disruption, including drilling holes and filling them. However, professional installers take precautions to minimise mess and ensure a tidy finish. Any debris or dust generated during the process should be cleaned up by the installers.

    My property has rubble in its cavities. Should I have cavity wall insulation installed?

    If your cavity contains rubble or other debris, it is recommended to have it cleared before installing cavity wall insulation. This ensures that the insulation material can be effectively injected into the cavity, maximising its performance and avoiding potential issues.
