Before we quote in Bangor (County Down)
Surveys in Bangor (County Down) also cover the surrounding BT19 district and towns such as Newtownards and Holywood. 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 terraced homes in Bangor (County Down) with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

Planning and building control in Northern Ireland

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.
