Solid wall insulation explained

‘Solid wall insulation’ is used on houses which were built without a cavity between the inner and outer wall. Such houses loose far more heat through their walls than houses with a wall cavity, especially if that cavity has insulation in it. The image below shows two semi-detached houses photographed with a special camera which records the amount of heat emitted from the homes over a few hours.

The house on the left has it’s central heating turned on, and the yellow and red patches show where significant amounts of heat are being emitted by the walls and windows. Insulation could prevent this heat loss and reduce the heating bills for the occupants.

The photographs below show insulation being installed on the outside of a house.

First the brickwork is fully exposed.

Then the insulation is applied to the brickwork.

Finally a plaster coat is put on top of the layer of insulation.

This photo shows insulation being fitted around a window

The insulation can be applied to the inside of the walls. This photo shows insulation being fitted around a window onto the internal wall of the house. It will then be plastered over.
