Cavity insulation for new builds and extensions for Inverness properties

Inverness sits in the Highlands and Islands. We work across the IV1 district, including nearby Nairn.

For semi-detached and terraced homes in Inverness, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Where an Inverness property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.

Wind-driven rain is the first thing the surveyor weighs up. Parts of the Highlands and Islands 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 Inverness 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.

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.
