Local Housing Stock
Property profiles in Castletroy
Castletroy features a varied housing stock. Homeowners with solid-wall properties (solid brick, concrete block, or stone construction) in Castletroy cannot pump their cavity walls and will benefit the most from EWI. Limerick features many solid concrete block homes built in the 20th century. EWI wraps these solid walls to stop heat escape. It is also excellent for brick terraced homes, replacing drafty walls with a fully insulated envelope.
Climate Challenges
Weather exposure in Castletroy
Like much of County Limerick, Castletroy 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.
