Cavity wall insulation for flats for Lisburn properties
Our County Antrim coverage takes in Lisburn (BT28) and nearby Belfast, Newtownabbey and Carrickfergus. It is roughly 7 miles south-west of Belfast.
Work on Lisburn rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Lisburn 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 Antrim 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 Lisburn inserting cavity wall insulation needs a building control application to the council before work starts.
Funding in Northern Ireland
In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

Fire and height
For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
