Slim Cavity Units for Barnstaple properties
Most Slim Cavity Units enquiries we take in Barnstaple start with an opening that is not a standard size. Local stock is dominated by cob and thatch, Regency seaside terraces and Dartmoor granite cottages, which sets the sizes and profiles we work to. What accelerates it is the wettest large county in England with severe Atlantic exposure, and sustained rot in cob-embedded frames and moor-exposed openings follows sooner than owners expect. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
The survey happens before manufacture, which is why our units fit without packing or trimming. Send what you have, even if it is only a phone photo, and we will take it from there.
Bear in mind for this area: cob walls move seasonally, so frames need tolerance built into the fixing detail.
