What the job covers
- Used on blocks of flats and buildings with storeys above 11m
- Better sound reduction than foam boards
- Vapour-open, so moisture in solid walls can dry outwards
- Heavier than EPS, so more fixings and careful handling

Newry: walls, weather and approvals
We also cover Banbridge and Armagh, close to Newry. It's roughly 43 miles from Newry to Bangor (County Down), the largest town in County Down. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Exposure to wind-driven rain varies across County Down: 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.
For homes in Newry near busy roads, mineral wool's sound reduction can be a reason to choose it.

Approvals in Northern Ireland
For Newry homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
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 Newry: 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.
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.
