Underfloor insulation in Stranraer

Underfloor insulation fits mineral wool or rigid boards between the joists of a suspended timber floor, supported on netting or battens, so cold air from the ventilated void below stops chilling the room. In Stranraer we follow the Scotland rules on building standards, and confirm the route on your quote.

Underfloor insulation for Stranraer properties

Our Dumfries and Galloway coverage takes in Stranraer (DG9) and nearby Castle Douglas.

We check ventilation as carefully as insulation in Stranraer homes, because both matter for keeping a house dry. Where a Stranraer home also has empty cavity walls, we can survey those at the same time.

On the rules side, if cavity wall insulation follows 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.

Keeping the void ventilated

Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.

What is included in Stranraer

  • Floor void inspection
  • Boards relaid
  • Draught sealing at skirtings
  • Insulation between joists
