Cavity Wall Insulation for Dublin 4 homes
Cavity fill applies mainly to Dublin 4's later 20th-century homes and some townhouses toward the docklands. The Victorian and Edwardian terraces of Sandymount and Donnybrook and the large period homes on Ailesbury and Shrewsbury Road have solid walls, which are insulated internally instead. We confirm construction at survey stage.
How homes in Dublin 4 lose heat
Large period homes have high ceilings, big sash windows, solid walls and suspended floors, so their heating demand is high and BERs of E to G are common despite good maintenance. Sandymount homes near the strand are also exposed to sea wind. Modern apartments mainly benefit from airtightness and ventilation checks.
Typical housing: Victorian and Edwardian red-brick terraces in Donnybrook, Sandymount and Sydney Parade, larger period semis and detached homes on Ailesbury and Shrewsbury, and modern apartments and townhouses toward the docklands.
Planning: Much of Dublin 4 is within Architectural Conservation Areas, and protected structures are common on Ailesbury, Shrewsbury and Pembroke Road.
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.
