What we look for in Kirkwall
Surveys in Kirkwall (KW15) are arranged around travel to the wider Orkney, Shetland and the Western Isles. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Orkney, Shetland and the Western Isles 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 Kirkwall near busy roads, mineral wool's sound reduction can be a reason to choose it.

Planning and building control in Scotland
Scottish householder rules mean many Kirkwall jobs that change the outside of a house need a planning application; we confirm the position before quoting.
Scotland's building standards cover changes to external wall construction; we check whether your job in Kirkwall needs a warrant.
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 Kirkwall: 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.
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 Kirkwall?
Yes — we survey and quote mineral wool external wall insulation in Kirkwall (KW15); island and remote addresses are surveyed by arrangement, with a fixed written price before any work starts.
