Blown mineral wool insulation for Sudbury properties
Sudbury sits in Suffolk, about 18 miles west of Ipswich. We work across the CO10 district, including nearby Haverhill, Bury St Edmunds and Stowmarket.
A suitable wall in Sudbury is usually filled in a single day from outside, with drill holes made good to match the pointing. Sudbury properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Local weather affects which walls can be filled. Much of Suffolk 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 Sudbury filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Why choose mineral wool?
Mineral wool fibres are treated to shed water, so moisture that gets into the outer leaf runs down the cavity rather than tracking across. It is classed as non-combustible, which matters for some flats and taller buildings, and it is usually the lower-cost certified option.
