Local Housing Stock

Property profiles in Sligo

Sligo 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 Sligo 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 Sligo

County Sligo experiences typical Irish weather, marked by high moisture levels, cold damp periods, and rain. Damp masonry conducts heat away from the home much faster. EWI acts as a waterproof shield, keeping the internal walls warm and dry, which eliminates damp and mould issues while keeping heating bills low.
