Bonded polystyrene bead insulation for Aberdare properties
If your property is in Aberdare or the CF44 district or nearby Rhondda, Merthyr Tydfil and Tonypandy, it is within our Mid Glamorgan coverage. It is around 16 miles north of Bridgend.
For semi-detached and terraced homes in Aberdare, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Aberdare properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Wind-driven rain is the first thing the surveyor weighs up. Parts of Mid Glamorgan 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 Aberdare filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
Funding in Wales

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.
