Local Housing Stock

Property profiles in Wexford

Wexford 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 Wexford 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 Wexford

County Wexford 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.

Planning & Council Regulations in Wexford

Planning Authority: Wexford County Council

In County Wexford, external wall insulation is generally considered exempted development under planning regulations, provided it does not change the essential character of the area. However, if your building is listed as a Protected Structure or lies in a Conservation Area, you should consult with Wexford County Council before beginning installation.
