Bonded polystyrene bead insulation for Antrim properties

Our County Antrim coverage takes in Antrim (BT41) and nearby Ballymena, Newtownabbey and Belfast. It is around 16 miles north-west of Belfast.

A suitable wall in Antrim is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Antrim, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Local weather affects which walls can be filled. 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.

On the rules side, in Antrim inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

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.

What is included in Antrim

  • Binder applied at the nozzle
  • Certified bonded bead system
