Blown mineral wool insulation for Hexham properties

Hexham is among the towns we cover in Northumberland, alongside Morpeth and Cramlington. It is around 25 miles south-west of Blyth.

For semi-detached and terraced homes in Hexham, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. If a wall in Hexham 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.

Exposure matters for every cavity wall. Northumberland 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.

On the rules side, in Hexham filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

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.
