Dunoon: walls, weather and approvals
Surveys in Dunoon also cover the surrounding PA23 district and towns such as Greenock and Helensburgh. Dunoon sits around 8 miles from Helensburgh. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Argyll and Bute fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Where a property in Dunoon is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Scotland: planning and regulations
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Scotland's building standards cover changes to external wall construction; we check whether your job in Dunoon needs a warrant.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.
