Local Housing Stock

Greystones property profiles

Wicklow features a unique range of properties, from coastal Victorian terraces in Bray to mid-century bungalows and mountain cottages. Many of these homes have solid block or stone walls with high U-values (poor insulation). EWI is particularly effective here as it wraps the external structure, preventing the driving rain from penetrating the walls and keeping the interior warm and dry.
