You can choose from four different materials when having cavity wall insulation installed, glass wool, rock wool, EPS beads and foam. Each type has its own pros and cons, but the main thing to look out for is the l-value, this is what dictates how well your insulation can inhibit heat loss from your home.
We would recommend using an installer who has been approved by the NIA or the CIGA, and who will give you a full guarantee to cover the work, this can be up to 25 years depending on the installer. You should also get a certificate to say that the work has been approved by your local authority, and the CIGA may come round as a spot check to make sure that the work was done to a high standard.
Can I have Cavity Wall Insulation in my timber-framed house?
You are likely to be able to have cavity wall insulation installed in your timber-framed house as long as the cavity between the walls is at least 50mm wide. If you are unsure, ask your energy assessor to come and have a look, or even better – get a professional insulation company to drill a small hole in the mortar and take a closer look. If you are unable to have cavity wall insulation installed, or the walls are not in good condition then it’s probably not a suitable option for your property.
Do Cavity Wall Insulations need a Building Regulation Approval?
It is essential that any insulation installation you have carried out is inspected by your local authority or CIGA and that they provide you with a certificate to say the work has been completed to a satisfactory standard. This will help to prevent any problems with damp in the future.
Generally speaking, cavity wall insulation will not cause damp problems unless the external brickwork or render is damaged after it has been installed, and this could be due to a number of factors such as incorrect installation, weather conditions or structural issues with the property. However, damp problems relating to cavity wall insulation usually occur because the walls cannot ‘breathe’ when insulated, causing condensation that eventually leads to penetrating damp.
