Homes and walls in Lurgan
We also cover Craigavon and Portadown, close to Lurgan. Lurgan is about 2 miles from Craigavon. 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 Armagh: 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 plan internal insulation in Lurgan homes room by room so you keep the rest of the house usable.

Approvals in Northern Ireland
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
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 Lurgan: questions
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.
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.
