Bonded polystyrene bead insulation for Daventry properties
Daventry is among the towns we cover in Northamptonshire, alongside Northampton, Market Harborough and Wellingborough. It is about 12 miles west of Northampton.
A suitable wall in Daventry is usually filled in a single day from outside, with drill holes made good to match the pointing. Where a Daventry property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Local weather affects which walls can be filled. Much of Northamptonshire 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.
For regulations, in Daventry 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.
