Bonded polystyrene bead insulation for Nailsea properties
Nailsea is among the towns we cover in Somerset, alongside Portishead, Clevedon and Weston-super-Mare. It is around 32 miles north-east of Taunton.
Nailsea properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Where a Nailsea property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. Somerset has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
For regulations, in Nailsea filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

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.
