The Government regards cavity wall insulation as one of the most effective energy savings measures that most people can carry out on their homes and apart from saving money it is also major contributor to reducing emissions of carbon dioxide through the conservation of fuel and power.
The injection of cavity wall insulation is a relatively simple process by which insulation is injected into this cavity through a series of holes. The injected insulation will have been designed so that any water that does enter the cavity can drain away, whilst the insulation still reduces the heat loss through the wall.
