What is Cavity Wall Insulation?

Cavity wall insulation is apparent in homes that are built after the 1920s. Cavity wall insulation can be installed by injecting insulation material into the cavity wall from the outside. Drilling small holes in the outside of the wall for access and then refilling over with cement. It is usually made from mineral wool or polystyrene beads. Cavity insulation costs vary depending on a number of factors. It depends on the size and age of your home. However, you should be able to make back the initial installation cost in less than five years due to the energy bill savings you are likely to make. Other cost-saving methods are available such as not insulting the whole home at once.

Making a Choice

Cavity wall insulation is guaranteed to minimise the loss of heat that can escape through the wall cavities by filling up the air spaces using insulation material to decrease the transfer of heat. By doing this it will not only stop the air in the cavities, but it will also reduce the cost of heating by a considerable amount. It does this by keeping the heat within the inner walls to keep the rooms warmer for a more extended period of time. This is usually a very common feature in houses, especially the ones that are built after the 1920s. Mineral wool, polyurethane foam and polystyrene beads are both materials that are often used for cavity insulation, and the one in which you select should be determined by the existing brickwork and how big or small in size your cavity is in your home.
