Homes and walls in Newtownards
We cover Newtownards and nearby Bangor (County Down), Holywood and Castlereagh. It's roughly 5 miles from Newtownards 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.
We compare EPS against mineral wool for each Newtownards enquiry rather than assuming one board suits every wall.

Permissions in Northern Ireland
In Northern Ireland, permitted development is set by the 2015 Order; in Newtownards, changing a house's external appearance, and any work on flats or listed buildings, may need permission, so we check with the council.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
How thick does the board need to be?
On a 225mm solid brick wall, around 90mm of grey EPS or 100–110mm of white EPS typically gets close to 0.30 W/m²K. Stone walls, concrete panels and hollow-block walls start from different points, so the system supplier's calculation for your wall sets the final thickness.

EPS insulation in Newtownards: questions
Is EPS insulation safe on a house?
EPS is used inside render systems that are fire-tested as a whole. On low-rise houses it is widely used. On taller buildings, or where guidance calls for non-combustible materials, mineral wool systems are specified instead.
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
How long does EPS last on a wall?
The board itself doesn't degrade when protected by the render system. Service life depends on the render, sealants and detailing, typically 25–30 years or more with maintenance.
