Part of every quote
- Finished in mineral or silicone render, or brick slip
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Vapour-open, so moisture in solid walls can dry outwards
- Heavier than EPS, so more fixings and careful handling
Local considerations in Bridgend
As well as Bridgend itself, we quote in Maesteg, Port Talbot and Rhondda. Bridgend sits around 12 miles from Rhondda. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
Older solid-walled homes in Bridgend can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Planning and building control in Wales
For homes in Bridgend, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
Wales applies its own external wall fire rules, updated in 2025; on taller residential buildings we specify non-combustible mineral wool systems.
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 Bridgend: questions
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.
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.
Do you cover Bridgend?
Yes — we survey and quote mineral wool external wall insulation in Bridgend (CF31) and nearby Maesteg, Port Talbot and Rhondda, with a fixed written price before any work starts.
