How does cavity wall insulation work. Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. Enjoy great prices on our range of loft insulation cavity wall insulation products. Our technicians drill 2cm holes into the outer wall then inject it with either bead or fibre cavity insulation.

It s straightforward and mess free when done by a cavity wall technician. Once the cavity is full the holes are filled in to match the existing wall. This involves blowing insulating material into the gap between the outside wall and the inside wall to reduce conduction. Reduced using cavity wall insulation.

Cavity wall insulation makes it much more difficult for heat to pass through your walls by filling up the cavity with a material with lots of small air pockets in it. This is a good way of preventing the inside wall. These pockets are more efficient at reducing heat transfer by convection than the big air cavity was. Physics index heat insulation.

Cavity wall insulation often has a layer of silver foil in order to reduce the heat lost by infrared radiation by reflecting it back into the building. Examples are loft insulation hot water tank and pipe insulation double glazing and cavity wall insulation see below. The cavity insulation guarantee agency was established in consultation with the government to provide householders with an independent uniform and dependable guarantee covering defects in materials and workmanship. There is an outside wall and an inside wall with an air gap between the two walls.
