Local Housing Stock
Property profiles in Westport
Westport features a varied housing stock. Homeowners with solid-wall properties (solid brick, concrete block, or stone construction) in Westport cannot pump their cavity walls and will benefit the most from EWI. Mayo 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 Mayo 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 Westport
Like much of County Mayo, Westport 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.
