Cavity Wall Insulation for Rathfarnham homes
The Nutgrove and Butterfield estates in Rathfarnham are typical 1960s and 1970s cavity-wall housing, and many still have empty cavities. A fill is one of the best value upgrades for these homes: done in a day, grant-aided and immediately noticeable. We check each cavity for debris and width first. Village homes near the castle have solid walls instead.
How homes in Rathfarnham lose heat
The mid-century estates are the bulk of the work here: cavity walls often built empty, 1970s-era attic insulation and suspended or uninsulated solid floors, usually rating D. The larger detached homes have more external wall area per room, so wall insulation makes a proportionally bigger difference.
Typical housing: Village stock and pre-war semis near Rathfarnham village, mid-century estate housing through Nutgrove and Butterfield, and larger detached homes toward Knocklyon and Templeogue.
Planning: The village core has conservation context; estate housing generally allows external insulation as exempted development.
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.
