Blown mineral wool insulation for Castle Douglas properties
If your property is in Castle Douglas or the DG7 district or nearby Dumfries, Annan and Stranraer, it is within our Dumfries and Galloway coverage. It is roughly 17 miles south-west of Dumfries.
Where a Castle Douglas property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. If a wall in Castle Douglas is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Every elevation is judged on its own exposure. Parts of Dumfries and Galloway 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.
As for paperwork, in Castle Douglas no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Why choose mineral wool?
Mineral wool fibres are treated to shed water, so moisture that gets into the outer leaf runs down the cavity rather than tracking across. It is classed as non-combustible, which matters for some flats and taller buildings, and it is usually the lower-cost certified option.
