Underfloor insulation for Larne properties
Our County Antrim coverage takes in Larne (BT40) and nearby Carrickfergus, Newtownabbey and Belfast. It is roughly 18 miles north of Belfast.
In Larne homes this is often done on the same visit as a cavity fill, which saves a second trip. Where a Larne home also has empty cavity walls, we can survey those at the same time.
For regulations, if cavity wall insulation follows in Larne, inserting cavity wall insulation needs a building control application to the council before work starts.

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
What is included in Larne
