When it comes to the proper insulation for your home, there are different options available. One particular option for homeowners is insulation in the cavity walls of the home, especially for houses that have been built after the 1920s, because this is when homes began to be constructed with a gap in between the outer walls and the inner walls. With the right cavity wall insulation, this gap can be filled, saving more energy and making the home’s temperature more comfortable.
How to determine if you need cavity wall insulation
First, you need to know if your home can benefit from this. If you are not sure about whether you have a cavity between your outer and inner walls, there are ways to determine this:
What you can expect to spend on installation costs
The installation costs for cavity wall insulation varies according to the building. With a detached home, you may spend around £700+ on installation, while with a semi-detached home, the cost of installation can amount to approximately £475. Cavity wall insulation for a mid-terrace house can be around £370, and for a flat, the installation cost can run to £330. But the good news here is that you may actually get cavity wall insulation for free, according to energy experts npower. It therefore pays to find out if you qualify for government initiatives so you need not spend on installation costs for your cavity wall insulation.
Your expected savings with cavity wall insulation
The savings you acquire with cavity wall insulation also depends on the type of building you have. If you have a detached house, then your annual savings can amount to as much as £250. For a semi-detached house and a mid-terrace house, your savings can reach £145 and £95 a year, respectively. Bungalows can expect savings of up to £100, while a flat can save around £75 every year.
But your savings from cavity wall insulation does not only extend to your energy bill – it also extends to your carbon footprint as well. With cavity wall insulation, a detached house can save up to 1,040 kilograms of carbon dioxide each year. A mid-terrace house can save 395 kilograms of CO2, while a semi-detached house can save around 600 kilograms every year. Meanwhile, bungalows and flats can save up to 410 kilograms and 325 kilograms of CO2 each year as well.
Consulting with a professional energy specialist will help you further when you are thinking of installing cavity wall insulation for your home. With the right advice and recommendations, you can make the proper decisions regarding your home’s insulation needs.
