Part of every quote
- Non-combustible board (typically Euroclass A1 or A2-s1,d0 as part of the system)
- Heavier than EPS, so more fixings and careful handling
- Vapour-open, so moisture in solid walls can dry outwards
- Used on blocks of flats and buildings with storeys above 11m
Homes and walls in Ballymena
Surveys in Ballymena also cover the surrounding BT42 district and towns such as Antrim and Magherafelt. Ballymena is about 23 miles from Belfast. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim 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 Ballymena can suit a vapour-open mineral wool build-up better than foam; the survey checks the wall first.

Northern Ireland: planning and regulations
Before quoting in Ballymena, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
On taller buildings in Northern Ireland we specify non-combustible mineral wool systems and confirm the classification with building control, in line with Technical Booklet E.
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 Ballymena: questions
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.
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 Ballymena?
Yes — we survey and quote mineral wool external wall insulation in Ballymena (BT42) and nearby Antrim, Magherafelt and Larne, with a fixed written price before any work starts.
