Homes and walls in Galashiels
Surveys in Galashiels also cover the surrounding TD1 district and towns such as Hawick and Kelso. It's roughly 13 miles from Galashiels to Hawick, the largest town in Scottish Borders. The Scottish Borders have stone-built towns and villages, rural cottages and some post-war estates.
Exposure to wind-driven rain varies across Scottish Borders: 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.
On blocks and taller buildings in Galashiels, mineral wool is the default because of the fire guidance for external walls.

Planning and building control in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Galashiels 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 Galashiels: 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.
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.
Do you cover Galashiels?
Yes — we survey and quote mineral wool external wall insulation in Galashiels (TD1) and nearby Hawick, Kelso and Peebles, with a fixed written price before any work starts.
