What is . . .

External Wall Insulation?


  • External Wall Insulation (EWI) offers a solution to homes constructed with solid walls to become more thermally efficient.


  • A layer of insulation is fixed to an existing wall and then finished with either a layer of render or an alternative cladding to protect the insulation.


  • An EWI solution can be engineered to suit practically any type of building design and construction, with established methods adopted for non-traditional housing, standard specifications of solid walls and more bespoke solutions for new build and many non-domestic situations.
