Insulating period and heritage homes from the outside
Older stone, cob and lime-built houses need systems that let the walls breathe, and consents where the building or area is protected.
What usually matters
- Breathable materials
- Listed building or conservation area consent
- Respect for the building's character
- Damp diagnosed before insulating
How we work
- Wood fibre and insulating lime render options
- Method statements for consent applications
- Survey of moisture and existing renders
- Honest advice where EWI isn't right
