Can I have Cavity Wall Insulation?
Modern houses are constructed with a cavity wall. This is where there is a gap between the wall on the outside of the house and the wall on the inside. Cavity wall insulation is used to reduce heat loss through a cavity wall by filling that air space. The insulation then slows down the heat escaping from inside your home through this gap to the outside wall because the warm air can’t move easily or quickly enough. It’s that simple really.
Cavity wall insulation has been around for some time now and most if not all new build properties since the late 1990’s are built with the insulation fitted between the inside and outside walls. It’s proven to work as long as the property is suitable to take the material and the job is done correctly. The suitability of your property will only be established when we ASSESS your property during our visit as we must insert a small camera into your wall to check everything is OK.
Cavity Wall Insulation is installed by drilling a set pattern of holes into the mortar joints on the outside of the property, and insulation is injected into the cavity from the bottom up. It can be very effective at retaining heat and saving you money, which in turn helps with your carbon footprint saving the planet!
Most of the work to install the insulation is done from the outside wall but cavity wall technicians do need to access your home to carry out safety checks or upgrade ventilation to your rooms or heating appliances. When the install is in progress the insulating material is injected into the wll through small holes drilled in the mortar joint of the wall. The bigger the property, the longer it takes to install the insulation, but most houses can be done in less than half a day.
If your walls are not suitable, for example if they are solid brick walls and they do not have a cavity gap at all or made of stone, we can look at other method of insulating them… Click to jump to Solid Wall Insulation for more information about how we can assist.
