External wall insulation is not a new concept, it’s actually been used across Europe since the 1960s. EWI is regarded as one of THE most effective ways to thermally upgrade existing buildings or to construct new buildings with energy efficiency in mind.
The versatility of the system may come as quite a surprise, with different types and thicknesses of insulants being able to deliver the efficiency results your project demands and a wide array of finishes in different colours, textures and effects which can satisfy even the most challenging of design briefs … brick, stone, render, texture, dash … it’s all possible!
