Slim Cavity Units for Peterlee properties

Half the Slim Cavity Units problems we fix in Peterlee started as a sizing assumption. You will find mostly colliery terraces, Georgian Durham city stock and Pennine stone housing in this area, and it moves as it ages. Then there is cold upland winters with heavy rainfall, which reliably produces frost and saturation damage on unmaintained painted softwood given enough seasons. The part that matters is narrow cavities that perform while keeping the sightline historic.

Nothing is ordered until someone has stood in front of the opening with a tape. Send what you have, even if it is only a phone photo, and we will take it from there.

Worth knowing locally: Durham's cathedral setting carries World Heritage-level design scrutiny.
