Professional External Wall Insulation Services in Cork 

At DG Plastering, we provide high-quality external wall insulation in Cork, helping homeowners improve energy efficiency, reduce heat loss, and protect their properties from the Irish climate. Our insulation solutions are designed to keep your home warmer in winter, cooler in summer, and more comfortable all year round, while also enhancing the external appearance of your property. 

With years of experience working on homes across Cork, we understand the challenges posed by older buildings, solid walls, damp conditions, and rising energy costs. Our external wall insulation systems offer a long-lasting, effective solution tailored to your home. 

What Is External Wall Insulation? 

External wall insulation (EWI) involves fitting an insulating layer to the outside of your home, which is then finished with a protective and decorative render. This system creates a continuous thermal barrier around the building, significantly reducing heat loss through the walls. 

External wall insulation is ideal for properties in Cork with solid walls, older houses, or homes that struggle to retain heat. In addition to thermal benefits, EWI also improves weather resistance and refreshes the exterior of your home. 

Benefits of External Wall Insulation in Cork 

• Improved Energy Efficiency 

        External wall insulation helps reduce heat loss, meaning your home stays warmer for longer. This can lead to noticeably lower heating bills and improved energy ratings. 

• Protection Against Irish Weather 
  

         Homes in Cork are exposed to wind, rain, and damp conditions. External wall insulation adds an extra protective layer to your property, helping to prevent moisture penetration and weather-related damage. 

• Reduced Damp and Condensation 

         By keeping walls warmer and allowing them to perform correctly, external wall insulation can help reduce condensation, damp issues, and mould growth inside the home. 

• Enhanced Appearance 

         External wall insulation gives your home a fresh, modern finish. A wide range of colours and textures are available to suit both traditional and contemporary properties. 

• Increased Property Value 

        A well-insulated home with improved energy efficiency and an upgraded exterior is more attractive to buyers and can increase overall property value.
