Before we quote in Stroud
We cover Stroud and nearby Gloucester, Cheltenham and Chipping Sodbury. It's roughly 8 miles from Stroud to Gloucester, the largest town in Gloucestershire. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Gloucestershire: 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 Stroud near busy roads, mineral wool's sound reduction can be a reason to choose it.

England: planning and regulations
Planning in Stroud follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
Is mineral wool required on my building?
For most two-storey houses it's a choice rather than a requirement. In England, regulation 7(2) bans combustible materials in the external walls of 'relevant buildings' 18 metres and over, and the Approved Document B guidance also covers residential buildings with a storey at 11 metres or more. Wales has its own amended rules, and Scotland restricts combustible cladding on buildings with a storey more than 11 metres above ground. We specify mineral wool wherever these apply and confirm the system's fire classification in writing.

Mineral wool EWI in Stroud: 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.
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.
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.
