External Wall Insulation (EWI) in Dartford, Kent

External wall insulation (EWI) from Polished Venetian wraps solid-wall Dartford and Kent properties in insulation board finished with a premium decorative render, cutting heat loss and refreshing the exterior in one project. It suits older homes without a cavity, and can reduce wall heat loss by around 30 to 40 percent.

Improve your home's energy efficiency and appearance with our comprehensive external wall insulation systems. Our EWI solutions combine high-performance insulation boards with premium decorative plaster finishes, effectively wrapping your property in a thermal blanket.

This eco-friendly plaster system not only reduces heat loss and energy bills but also transforms your home's exterior with attractive wall finishes. Particularly beneficial for older properties with solid walls, our finishes over insulation provide both practical and aesthetic benefits, often increasing property value while dramatically improving comfort levels.

EWI works especially well for older solid-wall homes across Dartford and Kent that were never built with a cavity for standard insulation. We finish every installation with our silicone render system, so you get the thermal upgrade and a genuinely smart-looking facade in the same project.
