Should perform the exact same and the system will be the same
I have just done my grandmothers house which had cavity wall insulation. We took images with a thermal image camera and it showed that the cavity wall insulation was not installed properly and the performance was terrible.
If you need info on the system and want us to calculate the U value etc give me a shout and I will pass it over to Mapei for you
As you say there can be a cavity insulation there, but if its not fitted correctly and full of cold spots it aint working.
Same as usual . You may have to drill through the first brick for your fixings,it depends in what conditions the bricks are.The same if is cblocks.How would ewi perform on a wall with a cavity compared to it on a solid wall?
