Lots of old and historic housing in Brighton & Hove and other places has large areas of uninsulated solid walls.
Solid walls tend to be cold, damp and a significant area of heat loss.
This webinar is by leading low energy architect Bob Prewitt who looks at how we can treat solid walls. The webinar was recorded as part of Eco Open Houses Online.
The webinar is two short films below:
- Talk where Bob discusses solid wall insulation
- Question and answer session.
Outline of solid wall insulation webinar:

Solid wall insulation webinar Q&A
Some of the questions asked included:
- In a terraced house, how much do you have to think about the walls with your neighbours? Does it matter how much they are insulated, if your neighbour is also heating their home?
- Do you have any advice on what may be substituted for insulated studs, if they are no longer available?
- Are there any solutions/materials that you may particularly recommend in relation to embodied carbon - e.g. carbon used in manufacture?
- Is there any point of just insulating the walls without getting below the floor boards and so not making rooms air tight?
