Homes and walls in Poole
We cover Poole and nearby Bournemouth, Christchurch and New Milton. Poole sits around 5 miles from Bournemouth. 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 Dorset: 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 Poole can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

England: planning and regulations
For a house in Poole, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Poole: 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.
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 Poole?
Yes — we survey and quote mineral wool external wall insulation in Poole (BH15) and nearby Bournemouth, Christchurch and New Milton, with a fixed written price before any work starts.
