Blown mineral wool insulation for Dumfries properties

Dumfries sits in Dumfries and Galloway. We work across the DG1 district, including nearby Annan and Castle Douglas.

Dumfries properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Most Dumfries 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.

Local weather affects which walls can be filled. Parts of Dumfries and Galloway face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, in Dumfries no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

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.

Is my Dumfries home too exposed for cavity insulation?
