Local Housing Stock
Property profiles in Clontarf
Clontarf features a varied housing stock. Homeowners with solid-wall properties (solid brick, concrete block, or stone construction) in Clontarf cannot pump their cavity walls and will benefit the most from EWI. Dublin features a large concentration of older solid-wall properties (solid brick or hollow-block construction) that cannot be insulated via cavity wall pumping. Dublin's suburban housing boom in the mid-20th century resulted in thousands of solid concrete block semi-detached houses. For these properties, wrapping the exterior in EWI is the gold standard, as it provides a continuous insulation layer, prevents thermal bridging, and updates the building's aesthetic completely.
Climate Challenges
Weather exposure in Clontarf
Like much of County Dublin, Clontarf experiences damp winters, frost, and high humidity. Wet masonry conducts heat away from the building envelope. Applying external wall insulation acts as a protective shield, keeping the building fabric dry and warm.

Planning & Council Requirements in Clontarf

Planning Authority: Dublin City Council / Fingal / Dún Laoghaire-Rathdown / South Dublin County Council
