Cavity wall insulation for landlords for Coleraine properties

Coleraine is among the towns we cover in County Londonderry, alongside Limavady, Magherafelt and Derry. It is around 27 miles east of Derry.

For commercial buildings in Coleraine, the survey also considers building use and fire requirements before a material is specified. Blocks of flats in Coleraine are surveyed as a whole, because the cavity runs across every flat in the building.

Wind-driven rain is the first thing the surveyor weighs up. 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.

For regulations, in Coleraine inserting cavity wall insulation needs a building control application to the council before work starts.
