If your property has cavity walls you may be considering installing insulation to save on heating costs, and keep the home warmer for longer. Adding this type of insulation is very straightforward and can be done by a professional installer. During the installation process, small holes are drilled into your external brick walls at regular intervals and then the insulation is blown into these gaps. This is very quick, simple and shouldn’t make much mess.
A third of all heat loss from a building is through the walls and adding insulation reduces this by trapping the warm air inside. This can also help you to cut your energy bills because the heating system doesn’t have to work as hard to keep the house warm.
It may be that the house is not suitable for cavity wall insulation, if it has a timber-framed structure for example. If this is the case you should speak to a damp proofing specialist before arranging the installation. This is because the installation of cavity wall insulation can actually create or contribute to a penetrative damp problem if it isn’t correctly carried out.
Cavity wall insulation cavity wall insulation near me is usually made of mineral wool or polystyrene beads, but other types are available too. It’s installed by drilling small holes into the exterior wall at regular intervals and then blowing the insulation in using special equipment. The installation should only take around two hours and once complete you should have a 25-year guarantee against the product failing.
The main reason that cavity walls were designed was to provide resistance to rain penetration – by having a gap between the inner and outer leaf, moisture is prevented from being able to travel straight through the wall to the interior. The main thing that can damage this resistance is the insertion of insulating material that bridges the gap between the inner and outer wall – for example, filling the cavity with material such as uncoated mineral wool or polyurethane foam.
This can lead to moisture getting into the timber framed structure and creating damp problems such as condensation, or even penetrative damp. This is due to the insulating materials acting as a moisture ’bridge’ and carrying the water through the timbers into the internal wall. Modern natural breathable insulation products are now available which can reduce this risk, or prevent it altogether.
