What you get
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Better sound reduction than foam boards
- Vapour-open, so moisture in solid walls can dry outwards
- Heavier than EPS, so more fixings and careful handling
Stranraer: walls, weather and approvals
Surveys in Stranraer (DG9) are arranged around travel to the wider Dumfries and Galloway. 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.
For homes in Stranraer near busy roads, mineral wool's sound reduction can be a reason to choose it.

Permissions in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Stranraer 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 Stranraer 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 Stranraer: 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 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.
Do you cover Stranraer?
Yes — we survey and quote mineral wool external wall insulation in Stranraer (DG9); island and remote addresses are surveyed by arrangement, with a fixed written price before any work starts.
