Local considerations in Dunoon
Surveys in Dunoon also cover the surrounding PA23 district and towns such as Greenock and Helensburgh. Dunoon is about 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.
On blocks and taller buildings in Dunoon, mineral wool is the default because of the fire guidance for external walls.

Planning and building control in Scotland
Scottish householder rules mean many Dunoon jobs that change the outside of a house need a planning application; we confirm the position before quoting.
Where a building warrant is needed for Dunoon work, it's obtained before installation starts, and the quote says who arranges it.
Scotland restricts combustible cladding on buildings with a storey more than 11 metres above ground, so taller buildings get non-combustible systems.
What about noise?
Dense mineral wool adds mass and absorbs sound, so homes beside main roads or railways often notice a quieter interior, particularly where windows are also upgraded. The improvement depends on the whole wall and windows, so we don't quote decibel figures without testing.

Mineral wool EWI in Dunoon: questions
Does mineral wool get wet?
It is water-repellent and protected by the render system. Like any insulation it must not be left exposed to rain during installation, so boards are covered and work stops in wet weather.
Is mineral wool better than EPS?
Not always better — different. Mineral wool wins on fire performance, breathability and acoustics; EPS wins on cost, weight and thinner boards for the same U-value. The wall, the building height and your priorities decide it.
Is mineral wool needed for a bungalow?
Rarely for fire reasons. It may still be chosen on a damp-prone solid wall where a vapour-open build-up is wanted.
