Cavity Wall Insulation for Naas homes
Naas's 1990s and 2000s homes were usually built with partial-fill cavity walls. Whether the remaining gap can be filled depends on its width and condition, which a borescope check settles. Where it can, a fill improves comfort and helps prepare the house for a heat pump. Town-centre period homes have solid walls.
How homes in Naas lose heat
The 1990s and 2000s estates were built under older building regulations with partial-fill cavities and modest attic insulation. They usually rate C, and the gains come from attic top-ups, checking cavity fill and sealing airtightness gaps. Town-centre homes have solid walls and need a different approach.
Typical housing: Town-centre period terraces and pre-war housing, with 1990s and 2000s estate housing across the wider catchment.
Planning: Town-centre conservation context can apply to older homes; estates generally 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.
