Would also be happy to come out horizontally from there with an EPS skirt but wondering how it compares cost wise with something like LECA.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16791&Focus=287324#Comment_287324 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=16791&Focus=287324#Comment_287324 Mon, 08 Feb 2021 21:17:55 +0000 djh Posted By: Dominic CooneyI suppose an uninsulated concrete floor slab (as in the current situation with this building) is always going to 'feel' cold compared to the room.
The feel of a surface is largely to do with its thermal admittance. Some surfaces, like concrete or stone, are inherently 'cold' because they conduct heat away from your hand or foot quite quickly. Timber or EPS or cork conduct heat away less rapidly and feel 'warm' because of this. Hence people like carpet and wood floors and cork mats in bathrooms etc. Changing the surface will be cheaper than installing UFH, although it doesn't do quite the same job.]]>
