Mineral wool external wall insulation in Inverness
From Inverness to Nairn, we price mineral wool external wall insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. Older solid-walled homes in Inverness can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.
- Free survey in IV2 and nearby
- Guide price from £125 per m² + scaffold, 0% VAT
- Fixed written price before work starts

Included as standard
- Vapour-open, so moisture in solid walls can dry outwards
- Heavier than EPS, so more fixings and careful handling
- Finished in mineral or silicone render, or brick slip
- Better sound reduction than foam boards

Homes and walls in Inverness
We cover Inverness and nearby Nairn, Forres and Elgin. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Highland 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.
For homes in Inverness near busy roads, mineral wool's sound reduction can be a reason to choose it.

Approvals in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Inverness we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Over-cladding work in Scotland often needs a building warrant from the council's building standards service, with Section 6 of the Technical Handbooks setting insulation benchmarks.
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 Inverness: 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.
Can mineral wool EWI have a brick finish?
Yes. Brick slips can be bonded over mineral wool systems designed for them, with additional fixings for the extra weight.
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.
Do you cover Inverness?
Yes — we survey and quote mineral wool external wall insulation in Inverness (IV2) and nearby Nairn, Forres and Elgin, with a fixed written price before any work starts.
