Cavity wall insulation is a great way to insulate your home and keep your heating costs down. The initial installation may seem costly, but it can be easily recouped through energy savings.
The type of property will also impact the cost of cavity insulation, for example a semi-detached home will have different requirements to a terraced house. The type of insulation is also important and there are a variety of different materials available ranging from rock wool to EPS beads and polyurethane foam. Each material has its own advantages and costs.
EPS beads have a very lightweight structure which makes them easy to install in your home. They are also a very green option as they can be recycled once they have reached the end of their life cycle. The price of EPS beads is around PS10-15 per square metre which makes it an affordable option for your home.
Glass wool is made from a mixture of mineral fibres which are bound together to form a sheet of insulation. It has a very high thermal performance and is rot-resistant. It has an attractive natural appearance and can be fitted to the outside of your home or inside your walls. It is available in different levels of quality, from HR to HR++.
The amount of time that it takes to install the insulation is a factor and can affect the overall cost of the work. Rendering your home will also have an impact on the cost as it can be more difficult to access the wall cavities and to make sure that all gaps are sealed. Cavity wall insulation cost
