Just bought a new property by the sea and was thinking of having an external wall insulation done on my walls rather than repainting the brickwork much of which is flaking off on the south elevation,Rendering was alo an option but that requires the complete removal of existing paint which would take me months to do.Just wondered what the cost would be give or take if anyone has had it done? .its a three bedroomed chalet bungalow so not huge walls.Webber Sto and Marmorit come to mind,Thanks
