Bonded polystyrene bead insulation for Castle Douglas properties

Castle Douglas is among the towns we cover in Dumfries and Galloway, alongside Dumfries, Annan and Stranraer. It is about 17 miles south-west of Dumfries.

Most Castle Douglas 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. A suitable wall in Castle Douglas is usually filled in a single day from outside, with drill holes made good to match the pointing.

Before any material is chosen, exposure is checked. 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.

In terms of approvals, in Castle Douglas 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.

What to know before you choose beads

Polystyrene is combustible, so beads are not the right choice for every building; height, use and nearby openings matter, and the system certificate sets the limits. PVC-sheathed cables in the cavity should be sleeved or kept out of contact with the beads where the certificate requires it. We check both at survey.
