If you would like more information about cavity wall insulation or loft insulation, contact us today.

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.

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.

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.

 

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.

 

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.

 

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.

Listed 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.

 

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.

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 time frame based on your specific situation.

 

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.

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.

 

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.

Installing loft insulation is a relatively simple process that can be done by homeowners themselves. It involves laying insulation material, such as mineral wool, between and over the joists in the loft space. However, if you are not comfortable doing it yourself, it is advisable to hire a professional installer.

 

Installing loft insulation can have several benefits for your home. It helps to reduce heat loss through the roof, making your home warmer and more comfortable. This also leads to energy savings and lower heating bills. Additionally, loft insulation can reduce noise transmission from outside, providing a quieter living environment.

Yes, it is recommended to clear your loft before installing insulation. This allows for easier access and ensures that the insulation is installed properly. Clearing the loft also provides an opportunity to de-clutter and organise the space, making it more suitable for storage if desired.

 

The time required to install loft insulation depends on various factors, such as the size of the loft and the type of insulation being used. On average, it can take a few hours to a full day to complete the installation. However, this can vary based on the complexity of the job and the experience of the installer.

Yes, you can still use your loft for storage after insulation installation. However, it is important to ensure that the insulation is not compressed or covered by stored items. Blocking the airflow around the insulation can reduce its effectiveness. It is recommended to use raised platforms or boards to create a storage area above the insulation.

 

Loft insulation is designed to last for many years, typically around 40 years or more. However, the longevity can vary depending on the type of insulation and its quality. It is advisable to periodically check the condition of the insulation and replace it if it becomes damaged or deteriorated.

Yes, loft insulation is considered environmentally friendly. It helps to reduce heat loss, which in turn reduces the amount of energy required to heat your home. By using less energy, you can reduce your carbon footprint and contribute to a more sustainable environment. Additionally, many insulation materials are made from recycled or sustainable materials.

 

Yes, building regulations do have an impact on loft insulation. In many countries, there are minimum standards and requirements for insulation installation, including loft insulation. These regulations ensure that insulation is installed to a certain standard of thermal efficiency and safety. It is important to check local building regulations and comply with them when installing loft insulation.

Loft insulation, when installed correctly, should not cause damp. In fact, it can help prevent dampness by reducing condensation and moisture build-up in the loft space. However, if insulation is installed incorrectly or if there are existing issues with dampness in the loft, it is possible for insulation to become damp. Proper ventilation and addressing any existing damp issues are essential to prevent moisture-related problems.
