Before we quote in Renfrew
We cover Renfrew and nearby Clydebank, Paisley and Bearsden. Renfrew is about 5 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.
Older solid-walled homes in Renfrew can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Scotland: planning and regulations
Scottish householder rules mean many Renfrew jobs that change the outside of a house need a planning application; we confirm the position before quoting.
Where a building warrant is needed for Renfrew 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 Renfrew: 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.
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.
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 Renfrew?
Yes — we survey and quote mineral wool external wall insulation in Renfrew (PA4) and nearby Clydebank, Paisley and Bearsden, with a fixed written price before any work starts.
