Internal solid wall insulation may be suitable for homes made from brick, stone or concrete and works by adding a layer of thermal material to the existing inside wall. Although insulation will reduce the size of your room, it’ll be warmer, so you’ll be comfortable and enjoy the space more.

Internal solid wall insulation is particularly appropriate where you need to maintain the external look of the building, such as a heritage site. Around half of all the heat lost from a typical solid-walled home escapes through the walls.

1. Insulated boards:

These come in various materials and thicknesses, which have different energy-saving properties. Some types have pre-attached plasterboard, which makes the installation process more straightforward.

2. Stud frames with infill:

Here, wooden or metal stud frames are fixed to the walls, insulation is fitted, and plasterboard is laid over the top. Various insulation materials, including mineral wool or sheep wool, wood fibre, hemp and recycled bottles, can be used. The battens can hold more weight than boards, so you can attach heavier items such as bookcases or kitchen cupboards. Rough and uneven walls – such as those found in some stone properties – can be made smooth and even in this way.

3. Insulated plaster:

This is a mix of plaster and insulating material, such as cork. Trowelled or sprayed on, it is a good option for uneven walls and can help achieve good levels of airtightness.

In an average 3-bedroom, semi-detached house, depending on the number of rooms being renovated and the type of insulation used. If this home used gas heating, the savings would be around £475 a year on heating bills in the region. A detached house could save around £603 per year (figures from the Energy Saving Trust and National Housing Model).
