Part of every quote
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Finished in mineral or silicone render, or brick slip
- Vapour-open, so moisture in solid walls can dry outwards
- Better sound reduction than foam boards
Wishaw: walls, weather and approvals
As well as Wishaw itself, we quote in Motherwell, Hamilton and Bellshill. It's roughly 10 miles from Wishaw to East Kilbride, the largest town in Lanarkshire. West Central Scotland has sandstone tenements, interwar and post-war council housing including no-fines and other system-built types, and many harled (roughcast) houses.
Exposure to wind-driven rain varies across Lanarkshire: 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.
Older solid-walled homes in Wishaw can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Approvals in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Wishaw 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.
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 Wishaw: questions
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.
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 Wishaw?
Yes — we survey and quote mineral wool external wall insulation in Wishaw (ML2) and nearby Motherwell, Hamilton and Bellshill, with a fixed written price before any work starts.
