Blown mineral wool insulation for Downpatrick properties

If your property is in Downpatrick or the BT30 district or nearby Newtownards, Banbridge and Bangor, it is within our County Down coverage. It is around 22 miles south of Bangor.

Most Downpatrick houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. For semi-detached and terraced homes in Downpatrick, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Wind-driven rain is the first thing the surveyor weighs up. Parts of County Down 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 the rules side, in Downpatrick inserting cavity wall insulation needs a building control application to the council before work starts.

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.
