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

Local considerations in Stanley
As well as Stanley itself, we quote in Chester-le-Street, Consett and Gateshead. Stanley sits around 24 miles from Darlington. The North East has many solid brick terraces, including former colliery housing, plus post-war council estates with some system-built homes.
Exposure to wind-driven rain varies across County Durham: 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.
For homes in Stanley near busy roads, mineral wool's sound reduction can be a reason to choose it.

Permissions in England
For a house in Stanley, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
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 Stanley: questions
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.
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.
Do you cover Stanley?
