Cavity Wall Insulation (CWI) is a type of insulation that can be installed into the external walls of your home to help increase its thermal efficiency. By insulating the space between your property’s outer and inner walls, heat loss is reduced dramatically, which means that your energy bills will decrease as well. It can also lead to a comfortable and more sustainable living environment, and it’s a great option for older properties or those in the process of undergoing a renovation. To find out more about this type of insulation and whether it would be suitable for your property, speak with a professional.
What is the best cavity wall insulation?
There are many different types of cavity insulation, including mineral wool, polystyrene granules and polyurethane foam. The best choice for you will depend on the size of your property, the width of the cavity and your budget.
Mineral wool is a popular choice for cavity insulation because it can be fitted using existing holes in the walls and doesn’t require the removal of internal plaster. It’s available in a range of thicknesses and is a good budget-friendly option, typically costing between PS18 and PS22 per m2. Polystyrene beads are another popular choice for cavity wall insulation. These are available in white, grey or black granules and can be purchased for PS18 to PS22 per m2. However, they aren’t as effective at thermal regulation as other options and may leak through any cracks or gaps in the walls.
One of the most significant benefits of cavity wall insulation is that it reduces condensation and dampness in your property. This is because the insulation acts as a barrier against moisture penetration, which can lead to a host of problems. Moreover, it will help to maintain a consistent temperature throughout the property and will prevent cold spots from developing.
Furthermore, the insulation will reduce external noise transmission into your home, which can be a real issue for those who live near busy roads or highways. This will lead to a much more peaceful and relaxing living environment, as well as helping you to sleep better at night.
Another benefit of cavity wall insulation is that it helps to reduce carbon emissions. By reducing your energy consumption, you’ll be relying less on non-renewable resources and thereby contributing to a greener future.
Is cavity wall insulation worth the investment?
In the long term, cavity wall insulation can save you a significant amount of money on your energy bills, as it will reduce the need to use heating and air conditioning systems. This can lead to substantial savings, especially with energy prices increasing steadily over the last few years.
Typically, the payback period for cavity wall insulation is around 2 years, and in some cases even shorter. This makes it an affordable solution that can save you thousands of pounds over the lifetime of your property.
Choosing the right insulation material and installer is crucial to getting the most from your CWI. By hiring a reputable insulation expert, making sure your property is ready for work and following maintenance guidelines, you can be confident that your new insulation will perform as expected for a long time to come.
