Hello about to embark on my first ewi job looking forward to it.it is a retrofit and there is concrete sills which are too small also a big cold bridge,so was wondering about different solutions my plan was cutting flush with existing render and insulating and put new upvc sill over the top. He isn't worried about keeping concrete sill but thinks over sills look tacky cheers for any advice again appreciate it also if any one has any pictures of doing this would be brilliant thanks ian
