Local considerations in Newtownards
Surveys in Newtownards also cover the surrounding BT23 district and towns such as Bangor (County Down) and Holywood. Newtownards is about 5 miles from Bangor (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.
Where a property in Newtownards is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Planning and building control in Northern Ireland
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Newtownards: questions
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
