Walls (retrofit)
Carrying out a responsible retrofit to a traditionally constructed, or historic building (originally built with lime and vapour-open brick, stone, timber or earth), means using only vapour-permeable insulations and finishes. In this way the original fabric performance is maintained, and the risk of moisture being trapped in the wall is eliminated. When choosing a material, it is important to consider what is most important for your specific project: affordability, thermal performance, or sustainability credentials, such as embodied carbon in the material.
