Before we quote in North Yorkshire
Yorkshire's housing includes stone and brick terraces, back-to-backs in parts of West Yorkshire, and post-war estates with steel-framed and concrete house types.
Exposure to wind-driven rain varies across North Yorkshire: 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.
Older solid-walled homes in North Yorkshire can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Planning and building control in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
Combustible materials are banned in the external walls of relevant buildings 18 metres and over (regulation 7(2)), and Approved Document B guidance also covers residential buildings with a storey 11 metres or more above ground. Higher-risk buildings go through the Building Safety Regulator.
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 North Yorkshire: questions
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.
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 all of North Yorkshire?
Yes. We survey and quote mineral wool external wall insulation across North Yorkshire, including York, Middlesbrough, Harrogate, Scarborough, Redcar.
Do I need planning permission in England?
