Local Housing Stock
Property profiles in Castlecomer
Castlecomer features a varied housing stock. Homeowners with solid-wall properties (solid brick, concrete block, or stone construction) in Castlecomer cannot pump their cavity walls and will benefit the most from EWI. Kilkenny has a varied mix of housing types, from older stone cottages and solid block farmhouses to modern housing estates. Many solid-wall properties in County Kilkenny suffer from high heat loss and dampness because they lack a cavity wall. External wall insulation is the most effective retrofit method for these properties, protecting the structural walls and dramatically boosting the BER rating.
Climate Challenges
Weather exposure in Castlecomer
Like much of County Kilkenny, Castlecomer 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.
