Bonded polystyrene bead insulation for Carrickfergus properties
We cover Carrickfergus and the BT38 postcode district, including nearby Newtownabbey, Larne and Belfast. It is around 9 miles north-east of Belfast.
A suitable wall in Carrickfergus is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Carrickfergus houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Wind-driven rain is the first thing the surveyor weighs up. Parts of County Antrim face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
As for paperwork, in Carrickfergus inserting cavity wall insulation needs a building control application to the council before work starts.

Where bonded beads make sense
Beads behave a little like a liquid as they go in, so they fill narrow and irregular cavities more evenly than fibre. The binder stops them pouring out if a brick is removed later. Some certified bead systems are approved for higher driving-rain exposure than fibre systems, which is why they are common on western and coastal elevations.
