Greenock: walls, weather and approvals
We cover Greenock and nearby Helensburgh, Dunoon and Clydebank. Greenock is about 20 miles from Glasgow. 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.
Parts of Greater Glasgow 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 Greenock 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 Greenock 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 Greenock 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 Greenock: 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 Greenock?
Yes — we survey and quote mineral wool external wall insulation in Greenock (PA15) and nearby Helensburgh, Dunoon and Clydebank, with a fixed written price before any work starts.
