Cavity wall insulation It will make your home warmer and help you save on heating bills, but how do you choose the right system? C avity wall insulation, in various forms, has been around since the seventies and during that time around six million existing homes built with cavity walls have had this installed. However, there are an equal number of properties with cavity walls that remain empty, which could greatly benefit from installation. Is cavity wall insulation any good? The simple answer to this often asked question would be to say that cavity wall insulation is very good, but only when installed properly. This article will explain what you should expect from having it installed, give you advice on choosing the right system, and tell you what to look out for during the installation process to ensure that you get what you pay for and also polypearl DPS.indd 190 to ensure that you achieve the highest possible energy saving in the coming years. Can cavity wall insulation really save the energy that installers claim it does? DID YOU KNOW Insulating your cavity walls can save you up to 25% on your heating bills By choosing the right system and ensuring correct installation it is possible to reduce your heating bills by approx 25% per year, which typically equates to around £350 in a detached house or around £200 in a semi-detached house. Therefore it is very important that you make an informed choice of which system you want to be installed into your property; make certain the installer is approved by the British Board of Agrément (BBA) to install that particular system, and then check out the installation process to make certain that the installer you entrust with the work does a good job. Choosing the right system When choosing the system to be installed, there are really only two criteria to consider: one, will the system give you the best possible return on your investment; and two, will the system maintain the same protection against winddriven rain that an empty cavity does. To get the best return on your investment, you will need to check that the chosen system can fully fill the cavity to an even density and that no voids form during the installation process.
