Adam2 Posted October 19, 2021 Share Posted October 19, 2021 Am I correct in thinking that this perimeter insulation strip used on the exterior of a floor screed is there for insulative benefits and not to do with expansion? If so, with all my external walls being EPS I can avoid having to install this? The floor build up if it matters: concrete slab, dpm layer, PIR, slip membrane, UFH pipes, 55mm screed Link to comment Share on other sites More sharing options...
tonyshouse Posted October 19, 2021 Share Posted October 19, 2021 Yes, screed seems thin, needs pipe sleeves and movement joints in doorways Link to comment Share on other sites More sharing options...

Though my question was really about the need for perimeter insulation given that the walls are EPS Link to comment Share on other sites More sharing options...
tonyshouse Posted October 19, 2021 Share Posted October 19, 2021 No need, possibly on internal walls if masonry Link to comment Share on other sites More sharing options...
