What size is cavity wall insulation?

Cavity wall insulation is one of the most practical ways to improve your property’s EPC rating and save energy. It reduces heat loss through walls and prevents draughts from entering your home. It can also protect you against rising fuel costs.

If you have a house built after the 1920s, there is a high likelihood that your external walls will be constructed with a cavity between two ‘skins’ of brickwork. These cavities are a common feature in properties across the UK and can be filled with insulating materials to increase your energy efficiency and comply with regulations.

The most popular types of insulating materials for cavity walls include rock wool and polystyrene beads. These are injected into the cavities using special equipment and an adhesive to ensure they remain in place. They are favoured over other types of insulating materials due to their size, which makes them easier to inject into small gaps and their ability to spread evenly within the cavity.

While there are different methods for installing cavity wall insulation, most of them involve drilling holes into the external walls of your property and subsequently pumping in the insulating material. This will either be rock wool which is laid or in some instances blown into the cavity or thin expanded polystyrene boards which are inserted between the bricks. Regardless of which method is used, the insulating material will offer insulation for the life of your property and can be installed either as partial or full fill depending on your preference.

If you decide to have cavity wall insulation installed in your property, it is recommended that you work with a company that is reputable and has a good track record. They will carry out a survey of your property before any work is carried out and this will help you to choose the right type of insulation for your needs and budget. They will also help you to determine whether your house is suitable for cavity wall insulation and offer advice on the best materials to use.

A well-insulated home is a comfortable and cost-effective home. Investing in cavity wall insulation can cut your heating bills and protect you against future fuel price increases. It is expected that the money you spend on cavity wall insulation will be recouped in your electricity bill within 2-3 years.

With gas and electricity prices constantly increasing, it’s important that you keep your energy bills as low as possible to protect yourself from the effects of higher fuel prices. Having cavity wall insulation installed in your home is a quick and easy way to cut your bills. It will significantly reduce the amount of energy you have to use in order to achieve a comfortable temperature and will also reduce your carbon footprint.
