Cavity insulation or Cavity wall insulation is a home insulation technique that can help you save energy, cut carbon emissions and save money on utility bills.

One of the major forms of heat loss in a house is through the walls. Approximately a third of all heat is lost through a building’s walls and cavity wall insulation can stop this heat escaping, which will save money on utility bills by about £115 a year in the average home, as well as reducing your carbon footprint. The other major heat loss in a home is through the roof, which can be limited through the installation of Loft Insulation.

A large proportion of homes in the UK are without cavity wall insulation. Homes built from the 1920’s onwards usually have cavity walls, which are often not insulated with cavity insulation. This means that houses are built using two layers of external walls with a gap or ‘cavity’ in the middle of the two walls. Cavity insulation or cavity wall insulation involves filling the gap or ‘cavity’ in order to insulate the building or home to save money on utility bills and in turn reduce carbon emissions.

Cavity wall insulation, like Loft Insulation is a very economically worthwhile and one of a number of simple energy saving techniques that can be easily employed in most homes, allowing anyone to save money on utility bills and reduce their carbon footprint relatively easily. On average, cavity wall insulation costs around £250 to install with the 50% subsidy available under the Carbon Emissions Reduction Target scheme, and with savings on utility bills and heating bill approximately £135 a year with the installation of cavity wall insulation, it means you will have made your money back on utility bill saving in less than two years. Having cavity wall insulation is also beneficial if you are looking at selling your home, as you will do better in your HIPS report, and your house will become more desirable to potential buyers. Having cavity wall insulation installed can also reduce carbon emissions produced by your house by 610kg a year for an average sized semi detached home. This is a great way to combat climate change, and if everyone in the UK took simple measures like this, a huge difference could be made. It is estimated that if every household who could install cavity wall insulation in the UK did, it would save the £690 million a year, and reduce CO2 emissions by a massive 4 million tonnes. This truly shows that every little bit people do can make a big difference overall.
