What the job covers
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Heavier than EPS, so more fixings and careful handling
- Finished in mineral or silicone render, or brick slip
- Vapour-open, so moisture in solid walls can dry outwards

Homes and walls in Chipping Sodbury
Surveys in Chipping Sodbury also cover the surrounding BS37 district and towns such as Yate and Mangotsfield. Chipping Sodbury is about 24 miles from Gloucester. 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.
Older solid-walled homes in Chipping Sodbury can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Permissions in England
Before quoting in Chipping Sodbury, 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.
What about noise?
Dense mineral wool adds mass and absorbs sound, so homes beside main roads or railways often notice a quieter interior, particularly where windows are also upgraded. The improvement depends on the whole wall and windows, so we don't quote decibel figures without testing.

Mineral wool EWI in Chipping Sodbury: 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.
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.
