Blown mineral wool insulation for Limavady properties

Limavady sits in County Londonderry, roughly 14 miles east of Derry. We work across the BT49 district, including nearby Coleraine, Derry and Magherafelt.

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

Exposure matters for every cavity wall. Parts of County Londonderry 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 Limavady inserting cavity wall insulation needs a building control application to the council before work starts.

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.
