Cavity insulation for new builds and extensions in Annan

Cavity insulation for new builds and extensions for Annan properties

Annan is among the towns we cover in Dumfries and Galloway, alongside Dumfries and Castle Douglas. It is about 16 miles east of Dumfries.

Where an Annan property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. If a wall in Annan 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.

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 Annan 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 we work from

Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.

What is included in Annan

  • Photo record for building control
  • Coordination with your bricklayers
  • Trays, closers and stop ends as drawn
