Blown mineral wool insulation for Chichester properties
We cover Chichester and the PO19 postcode district, including nearby Bognor Regis, Littlehampton and Worthing. It is around 32 miles south-west of Crawley.
For semi-detached and terraced homes in Chichester, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. If a wall in Chichester is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Before any material is chosen, exposure is checked. West Sussex 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 Chichester filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
