Bonded polystyrene bead insulation for Lisburn properties

If your property is in Lisburn or the BT28 district or nearby Belfast, Newtownabbey and Carrickfergus, it is within our County Antrim coverage. It is about 7 miles south-west of Belfast.

If a wall in Lisburn is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. A suitable wall in Lisburn is usually filled in a single day from outside, with drill holes made good to match the pointing.

Exposure matters for every cavity wall. 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.

For regulations, in Lisburn 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.
