Blown mineral wool insulation for Stranraer properties

If your property is in Stranraer or the DG9 district or nearby Castle Douglas, it is within our Dumfries and Galloway coverage.

For semi-detached and terraced homes in Stranraer, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Stranraer properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.

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.

In terms of approvals, in Stranraer 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.

What is included in Stranraer

  • Cavity barriers where needed
  • Regulations route and guarantee named on the quote
  • Density and drill pattern recorded
