Cavity insulation for new builds and extensions in Dundee

Cavity insulation for new builds and extensions in Dundee starts with a free survey of the property, then a written result and a fixed price before any work is booked. 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 for Dundee properties

Our Tayside coverage takes in Dundee (DD1) and nearby Forfar, Arbroath and Perth. Dundee is one of the main towns we cover in Tayside.

A suitable wall in Dundee is usually filled in a single day from outside, with drill holes made good to match the pointing. Where a Dundee property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.

Before any material is chosen, exposure is checked. Tayside 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.

On the rules side, in Dundee 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.
