Cavity Wall Insulation – How to Find a Qualified Cavity Wall Installer

Cavity wall insulation is a cost-effective way to make your home more energy efficient. You’ll notice reduced heating bills straight away, and the investment will pay for itself in around three years. In addition, you could be eligible for government funding to help you afford energy saving improvements like cavity wall insulation.

The first step is to check whether your house has cavities. The best way to do this is ask a reputable installer to carry out a pre-installation survey at a convenient time for you and your family. They’ll use a boroscope, which involves drilling a small hole and looking at the brickwork inside to see if the wall has cavity space. The survey will also look at the condition of the external walls and any existing insulation, and it will ensure that your property is suitable for cavity wall insulation before installation begins.

Once the survey is complete and you’ve chosen your installer, they will arrange a convenient time to come and install the insulation. The insulation they’ll use is either expandable polystyrene foam (or sometimes bonded beads) and it is water resistant, rot-proof and will last the lifetime of your house.

Before the insulation is installed your installer will drill a series of small holes in your outer wall and blow the insulant into them using special equipment. It’s a quick process, and there’s no mess left behind when they’re finished. It’s important to check with your installer that they are CIGA registered so you can be sure that their work is carried out to the stringent technical standards required by CIGA and building regulations. cavity wall installer
