- Used on blocks of flats and buildings with storeys above 11m
- Better sound reduction than foam boards

Local considerations in Bracknell
We cover Bracknell and nearby Crowthorne, Wokingham and Sandhurst. It's roughly 10 miles from Bracknell to Reading, the largest town in Berkshire. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Berkshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
Older solid-walled homes in Bracknell can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Planning and building control in England
Before quoting in Bracknell, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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 Bracknell: 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.
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.
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.
