Cavity Wall Insulation
If your home has cavity walls, Insulation can be fitted between the two layers of brickwork or between brick and breeze block. The material typically used by Installers on the Grant scheme is a shredded mineral wool (glass fibre).
Small holes are drilled through the T joints in the mortar and the Insulation is blown in. Once the cavity is filled to the correct density, the machine cuts off. The Insulation must be installed from the bottom of the walls to the top so if you live in a flat, your neighbours above and/or below will also need Insulation.
