Cavity insulation for new builds and extensions in Fife

We arrange cavity insulation for new builds and extensions throughout Fife, from Dunfermline to Kirkcaldy and Glenrothes. For new walls the cavity is insulated as it is built, using full-fill mineral wool batts or partial-fill boards fixed to the inner leaf.

Cavity insulation for new builds and extensions across Fife

We cover 3 towns in Fife: Dunfermline, Kirkcaldy and Glenrothes.

Wind-driven rain is the first thing the surveyor weighs up. Fife has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

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

Building standards in Scotland

In Scotland, work associated with thermal insulating material within a wall is listed in schedule 3 of the Building (Scotland) Regulations as work that does not need a building warrant. It must still meet the building standards, so the survey still checks that the wall and the chosen material are suitable, including exposure to wind-driven rain.

Funding in Scotland

  • Home Energy Scotland is the starting point for the Home Energy Scotland Grant and Loan and for Warmer Homes Scotland, which can include cavity wall insulation.
  • Many councils also run area-based schemes for insulation in particular streets or estates.
  • ECO4 runs until 31 December 2026 across Great Britain, including Scotland.

Extensions that join an older house

Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.

What is included

  • Batts or boards to the specified U-value
  • Clean-cavity working
  • Trays, closers and stop ends as drawn
  • Coordination with your bricklayers
  • Photo record for building control
