Cavity Wall Insulation for Wicklow Town homes
Wicklow town's mid-century and newer homes often have cavities that can be filled. Exposed harbour-side and elevated homes may not suit a fill because of severe driving rain, and for those external insulation is the safer choice. We assess exposure as part of every survey.
How homes in Wicklow town lose heat
Harbour terraces are exposed to strong sea wind and driving rain, which matters for wall insulation choice: exposed cavity walls may not suit a fill, and external insulation often makes more sense. Mid-century homes typically rate D, newer estates C.
Typical housing: Town-centre period housing and Victorian terraces near the harbour, mid-century estates through the middle of the town, and 1990s and 2000s estates on the outskirts.
Planning: Town-centre conservation context can apply to older homes.
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.
