Blown mineral wool insulation for Castleford properties

Castleford sits in West Yorkshire, roughly 9 miles south-east of Leeds. We work across the WF10 district, including nearby Pontefract, Lofthouse and Wakefield.

A suitable wall in Castleford is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Castleford houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.

Wind-driven rain is the first thing the surveyor weighs up. West Yorkshire 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.

In terms of approvals, in Castleford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

When is it not the right choice?

Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
