Bonded polystyrene bead insulation for Cambridge properties
We cover Cambridge and the CB1 postcode district, including nearby Newmarket, Ely and Huntingdon. Cambridge is one of the main towns we cover in Cambridgeshire.
Where a Cambridge property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. For semi-detached and terraced homes in Cambridge, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Before any material is chosen, exposure is checked. Much of Cambridgeshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, in Cambridge 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.
