Lisburn: walls, weather and approvals
We cover Lisburn and nearby Belfast, Castlereagh and Newtownabbey. Lisburn sits around 7 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.
Where a property in Lisburn is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Northern Ireland: planning and regulations
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.
