- Finished in mineral or silicone render, or brick slip

What we look for in Dumfries
We cover Dumfries and the wider Dumfries and Galloway; island and remote addresses are surveyed by arrangement. South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Dumfries and Galloway 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 Dumfries, mineral wool is the default because of the fire guidance for external walls.

Permissions in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Dumfries we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Where a building warrant is needed for Dumfries 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.
Why choose mineral wool over EPS?
Two reasons come up most: fire and moisture. Mineral wool doesn't burn, which is why guidance for taller residential buildings points to non-combustible external wall materials. It is also vapour-open, so a solid wall that holds some moisture can keep drying outwards through the insulation and render.
The trade-offs are weight and cost. Slabs are denser, need more fixings and take longer to install, so the price per m² is higher than EPS.

Mineral wool EWI in Dumfries: 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 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.
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.
