Solid Wall Insulation
The insulation of solid walls is considerably more difficult than the insulation of cavity walls. Due to the lower potential savings and higher cost of undertaking the work it is best to incorporate the insulation of solid walls into major internal repair of the interior or exterior of the dwelling. Furthermore the work, although it can be done whilst the occupants remain in residence, is substantially more disruptive than the process of insulating cavity walls.
There are two methods of insulating solid walls:
1. Internal Solid Wall Insulation
This is also known as insulated dry lining and consists of a layer of insulating material installed behind a layer of plasterboard. It is applied from the inside and necessitates the removal of all fittings affixed to the walls - radiators, skirting boards, architraves etc.
2. External Solid Wall Insulation
The use of an insulating material to effectively wrap the wall. It is installed from the outside and typically a scaffold will be required. This type of installation method will necessitate the removal and reinstatement of rainwater systems and anything attached to or passing through the external walls of the property such as boiler flues, overflow pipes, telephone cables etc. Adjustments will also need to be made to window sills and doors as the wall is effectively being made thicker from the outside than it was prior to insulation.
