Blown mineral wool insulation for Dumbarton properties

If your property is in Dumbarton or the G82 district or nearby Clydebank, Bearsden and Bishopbriggs, it is within our Dunbartonshire coverage. It is roughly 7 miles north-west of Clydebank.

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

Every elevation is judged on its own exposure. Parts of Dunbartonshire 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.

On compliance, in Dumbarton no building warrant is needed for insulation within a wall, but the work must meet the building standards.

When is it not the right choice?

Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
