Cavity Wall Insulation

Cavity wall insulation is installed in the gap (cavity) between the inner and outer walls of a building. It helps to reduce heat loss through the walls by filling this gap with insulating material. Typically, cavity wall insulation is made from materials such as mineral wool, foam boards, or polystyrene beads. It can significantly improve the energy efficiency of a building and reduce heating costs.

External wall insulation (EWI) is often chosen for solid walls because it improves thermal performance without reducing internal floor space. By insulating the building from the outside, it helps retain heat more effectively, lowers U-values, and can enhance overall energy efficiency. EWI also protects the structure from weathering and can improve the external appearance of a property, while minimising disruption to occupants during installation since most of the work is carried out externally.

Floor insulation in the home can be a vital component for enhancing energy efficiency and comfort. By insulating your floors, you can significantly reduce heat loss, which helps maintain a consistent indoor temperature and lower energy bills. It acts as a barrier against cold drafts and dampness, particularly in properties with uninsulated floors over crawl spaces or basements. Proper floor insulation not only improves thermal performance but also contributes to a quieter living environment by reducing noise from below. Ultimately, floor insulation is an effective way to ensure a warmer, more energy-efficient, and comfortable home year-round.

Internal wall insulation involves adding insulation to the interior surface of external walls within a building. This can help improve the thermal efficiency of a property by reducing heat loss through the walls. Internal wall insulation is commonly achieved using materials like rigid foam boards or insulated plasterboard, which are fixed to the existing wall surface.

Loft insulation is typically installed in the space between the roof and the ceiling of the top floor of a building. It helps to prevent heat from escaping through the roof, keeping the space below warmer in the winter and cooler in the summer. Loft insulation is often made from materials like fiberglass, cellulose, or mineral wool and is available in rolls or batts.

Room in roof insulation, also known as attic or roof space insulation, involves insulating the space directly under the roof of a building that is used as a living area or storage space. This type of insulation helps to keep the space below more comfortable by reducing heat loss through the roof. It can be installed using various insulation materials, such as fiberglass, cellulose, or foam boards, depending on the specific requirements of the roof structure and building design.

Got A Question About Insulation?

What is insulation, and why is it important?

Insulation is a fabric measure which is used to seal the building and retain the heat within your property.

We provide multiple insulation measures, depending on each property’s eligibility via the government grant schemes.

Loft Insulation: This is usually wool loft insulation roll, which is rolled out in-between joists in the property’s loft, and cross-laid to provide full coverage and government-set required depths.

Internal Wall Insulation (IWI): This is foam-backed battens that are fixed to the walls at set intervals. We then friction-fit the IWI between each batten to ensure full coverage of the wall. We then install a Vapour Control Layer (VCL) which allows the wall to release moisture. Finally, we then cover with plaster boards and seal the edges with an airtight sealant, before plastering.

Cavity Wall Insulation (CWI): This is installed via a series of drill holes, which fills the cavity between each wall with expanding polystyrene beads. The wall is then sealed with mortar to prevent the beads escaping. Once completed, this retains the heat. It’s important to note that this method is subject to survey and pre-approval from the IAA.

Underfloor insulation is also available but very minimal in the government schemes currently available.

Yes. Both GBIS and ECO4 cover insulation measures. Simply apply today to see if you are eligible for a free insulation grant. If eligible, then you will receive these improvements to your home completely free of charge and depending on the scheme, sometimes in conjunction with other heating measures.

This will be discussed as part of your property’s retrofit survey. Also, an existing EPC may recommend installation or a top-up of the current insulation measures.

Insulation can last up to 80 years, where advised, but the warranty is usually 25 years from the manufacturers.

By retaining the heat and keeping the rooms to a certain temperature, insulation can help prevent moisture issues. However, this is also supplemented in the scheme with ventilation measures such as extractor fans and trickle vents. The fresh air coming into the property and the removal of polluted air helps prevent moisture issues.

Installing insulation measures reduces carbon emissions and energy bills as they reduce heat loss and maintain indoor temperatures. This reduces your reliance on heating systems, therefore reducing usage and the bills associated.

Loft insulation usually takes half a day to install.
Internal Wall Insulation (IWI) takes between 3-5 days to install.
Cavity Wall Insulation (CWI) usually takes half a day to install.
