Underfloor insulation in Dunoon

For homes and buildings in Dunoon, underfloor insulation is arranged survey-first: we check the property, tell you plainly what we found, and price it. 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.

Underfloor insulation for Dunoon properties

Our Argyll and Bute coverage takes in Dunoon (PA23) and nearby Helensburgh and Oban. It is about 8 miles south-west of Helensburgh.

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

In terms of approvals, if cavity wall insulation follows in Dunoon, 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 Dunoon

  • Insulation between joists
