Cavity Wall Insulation in Goatstown
Bonded bead or mineral fibre injected into empty cavities, usually done in a day with no mess inside. Covering Goatstown, Clonskeagh, UCD and the surrounding area.
Cavity Wall Insulation for Goatstown homes
Goatstown's mid-century estates toward Mount Merrion have cavity walls that are usually suitable for filling, while the period semis toward Clonskeagh and some post-war detached homes have solid or hollow-block walls. We confirm your wall type before recommending a fill, then inject bonded bead from outside in a single day.
How homes in Goatstown lose heat
The mix of stock means a mix of wall types: solid brick in the older semis, hollow block or early cavity in the post-war homes and cavity in the estates. Getting the wall type right is the key first step here, which a survey settles quickly. Ratings range from C3 in upgraded estate homes to F in untouched period semis.
Typical housing: Period semis toward Clonskeagh, post-war detached homes through the centre, and mid-century estate housing toward Mount Merrion.
Planning: Older streets toward Clonskeagh can carry conservation context; most other homes allow external insulation.
How cavity wall insulation works
Most Irish houses built from the 1960s onwards have cavity walls: two leaves of block with a gap between. Many were built with the cavity empty or only partly filled, which lets heat escape straight through. Filling the cavity is one of the best value upgrades available.

How do I know if my walls have a cavity?
Most Dublin homes built from the 1960s on do. A borescope inspection through a small hole confirms the cavity width and whether there is any insulation in it already.
Can cavity insulation cause damp?
Problems come from filling unsuitable walls, such as very exposed elevations or cavities blocked with debris. That is why we inspect first and only fill walls that are suitable.
Is there any mess inside the house?
No. All drilling and injection is done from outside. Inside, the only change is that the walls feel warmer.
