How to Tell If Your House Needs Cavity Wall Insulation

If the air spaces in your walls are at least 5 centimetres, then you need cavity wall insulation to reduce the amount of heat that is lost through the cavities. Also, you know you need cavity wall insulation if your house is 40 years old or more as elder houses are normally not as efficiently insulated as the new homes.

The Importance Of Cavity Wall Insulation

Reduction of heat loss – One of the main advantages of cavity wall insulation is that it helps to minimise the amount of heat that is lost through the air spaces in the walls. During the winter months, heat is lost through a method known as convection. By filling the air spaces with cavity wall insulation, it takes longer for the heat to pass through by trapping it within the walls.

Reduction of energy costs – When cavity wall insulation is filled in the air spaces within the walls, it helps to reduce heat loss hence reducing energy costs. This means that the running time for the heaters can be reduced, hence lowering the energy bills. It, therefore, improves the Energy Performance Certificate Rating of your house. The materials that are filled within the cavities can be recycled. This means that the costs of the installation of the insulation materials are lower.

More Benefits Of Insulation

Prevention of mould – Mould appears as a result of condensation. Cavity wall insulation can help prevent this issue. What happens is that the insulation helps to restrict moisture from passing through the wall. The materials used to fill the spaces are usually non-porous. This means that water cannot pass through the materials. Therefore, when the water is trapped within the walls, it runs down to the ground instead of going through the inner wall and letting moisture get into the exterior walls, hence causing the growth of mould.

Warmer houses – Since cavity wall insulation helps to prevent the loss of heat, it assists in keeping the temperatures inside the house warmer. This also means that there will be no need to keep the heaters running for long hours. It, therefore, also helps to lower energy bills.

Diameter size – The insulation material that is used in cavity wall insulation is referred to as polystyrene bead. This material is so small that it can be pumped into the cavities of the wall and allowing it to evenly sit inside the cavity. This also means that the size of holes drilled in the walls stay within the mortar line and are pointed up with the best possible colour match.
