What's included
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Used on blocks of flats and buildings with storeys above 11m
- Better sound reduction than foam boards
- Vapour-open, so moisture in solid walls can dry outwards
Dundee: walls, weather and approvals
We cover Dundee and nearby Forfar, Arbroath and Blairgowrie. Tayside has stone tenements and terraces in the towns, harled cottages and post-war estates.
Exposure to wind-driven rain varies across Dundee and Angus: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For homes in Dundee near busy roads, mineral wool's sound reduction can be a reason to choose it.

Approvals in Scotland
For Dundee properties, flats and tenements need planning permission for external insulation, and a noticeable change of finish on a house often does too under Scottish rules.
Scotland's building standards cover changes to external wall construction; we check whether your job in Dundee needs a warrant.
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 Dundee: questions
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.
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.
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.
Do you cover Dundee?
Yes — we survey and quote mineral wool external wall insulation in Dundee (DD1) and nearby Forfar, Arbroath and Blairgowrie, with a fixed written price before any work starts.
