Can I insulate the walls in my existing property?

Yes. Blown-infibreglass can be installed in retrofit applications to help reduce heat loss and make your home more energy efficient. Retrofit applications can be installed from the interior or exterior of the home. Interior installations will require the use of a 2″ hole saw to drill into each cavity in order to blow insulation into the wall. If you are already in the process of renovating your home and can remove any existing drywall or panelling, the installation can be done in the same way as new construction. Exterior retrofit installation can be achieved using a 2″ hole saw through the exterior walls; but,you if are able to remove the exterior finishing so the cavity is accessible to us, there won’t be a need to drill into the exterior of your home. The holes created will be plugged with wood which can be painted. There are no guarantees for results with retrofit construction. There are lots of factors that can affect the install, such as how much insulation is already present, if the existing insulation has saggedand moved, how accessible the area is, and if a working air barrier is still in place.
