Improved Thermal Efficiency with Cavity Wall Insulation
Insulating your home results in £450 yearly energy savings.
Cavity Wall Insulation
Properties in the UK that are built after the 1920s typically have cavity walls. Cavity walls are named for the gap in between their two wall layers. It is in this cavity, that insulation material can be injected
While cavity walls are generally better insulated than solid walls, their thermal efficiency can still be improved drastically through Cavity Wall Insulation. The added insulation will help lower your energy bills and aid in combating mould and condensation.
Cavity Wall Insulation involves filling the gap between your walls with the insulation material of your choice. You can choose from mineral wool, polystyrene beads, and foamed insulants.
To insert the insulation material into the wall cavity, small holes around 23 millimeters in size must be drilled in the mortar joints of your walls. For maximum coverage, the holes should be roughly 1.5 meters apart.
Once the holes are drilled, the installers will blow the insulation into the cavity using specialized equipment. Once the cavity is full of insulation material, the holes must be filled-in, to prevent moisture from seeping in. The entire process takes about 2 hours and if done properly, no further maintenance will be needed.
