Interior Wall Insulation
Solid wall insulation may be suitable for homes made from brick, stone or concrete construction, and works by adding a layer of thermal material to the existing inside wall. This will reduce the size of your rooms a bit, though you may find if a cold wall is made warmer you actually increase the amount of usable space in a room.
Internal solid wall insulation is particularly appropriate where you need to maintain the external appearance of the building (e.g. in a heritage context).
How do I know if my home has solid walls?
If your home is made of brick, and the bricks have an alternating long-short-long pattern like this, then the walls are likely to be solid. If you can see only the long edge of the bricks, like this, then they are almost certainly cavity walls.
If the brickwork is not visible, measuring the thickness of the wall at any entrance or window will help to determine the construction type. A solid brick wall is usually about 22cm thick, a cavity wall between 27cm and 30cm and a solid stone wall as much as 50cm thick. The age of your home can also be a good indicator; if it was built before the late 1920s it is likely to have solid walls.
Adding insulation to the internal walls can mean replacing the woodwork around sash windows like these
Types of internal solid wall insulation
There are various ways to insulate a solid walled building from within, but they broadly fall into four categories:
Most solid walls were built to be ‘vapour-open’ meaning that moisture can pass through the wall. If we insulate with ‘vapour-closed’ materials (such as foil-faced insulation foam) we risk trapping moisture inside the wall which could lead to damp, mould and damage to the building. If the existing wall is vapour-open you should always use vapour-open insulation materials, plasters and paints. Suitable insulation materials include woodfibre, mineral boards and cork. These should always be plastered with a lime-based finish and painted with vapour-open paints.
