In a typical building 35% of the heat is lost through the walls of your home, with good cavity wall insulation this loss can be reduced and save you money on your fuel bills.
Most houses that were built after 1920 have a cavity wall. The air filled cavity between the exterior and interior wall was purposely built to prevent rain that falls on the outside of the wall from crossing to the inside of the wall. This gap can now be filled with thermal insulation to reduce your fuel bills and carbon emissions. There are several benefits to installing cavity wall insulation:
Installing cavity wall insulation and loft insulation are considered among some of the most effective energy efficient measures available to today’s homeowners. This means that you save money on your fuel bills – the Energy Saving Trust (EST) estimate that you can save up to £110 per year by installing cavity wall insulation.
Over 35% of the UK’s carbon dioxide emissions, the main greenhouse gas which causes climate change, comes from everyday things in your home. Therefore, another benefit of cavity wall insulation is that it will cut down your carbon emissions. According to the EST, installing cavity wall insulation can save 560kg of CO2 per year.
There is always some moisture in the air, even if you cannot see it. When warm, moist air hits a colder surface such as the windows or walls, beads of condensation are formed, which can cause serious damp problems. Cavity wall insulation reduces condensation as the interior wall is warmer than that of an un-insulated cavity wall. One thing to note is that you must not block permanent vents when installing cavity wall insulation.
Having cavity wall insulation professionally installed will immediately impact the value of your home. It’s a good choice of home improvement and you will also be prepared if ever you want to sell your home and need to provide an Energy Performance Certificate (EPC).
