Cavity wall insulation can't be done by home owners. It will need to be carried out by trained technicians. The first step to getting your cavity insulation is to contact an insulation company to get a survey completed. The survey will determine which walls need to be insulated.

The process of installing the insulation is quiet simple. The technicians will make small holes on the outside of the building that extend into the cavity between the layers of brick. The technicians, will then inject the insulation material into the cavity. The whole process takes about 3 hours to carry out.
