clever perimeter insulation product

zacmobile Member Posts: 211
watch this youtube video of an italian radiant floor installation and check out the blue stuff around the perimeter, it's a neat perimeter insulation/expansion stripping product looks to be about 1/4" or 3/8" thick with a peel n' stick backing, does anyone know of something like this available in north america?? would help the problem of battling with builders about perimeter insulation. (In another video they isolate each room with it too, would make for more effective zoning)

PS: check out the 3" spacing, nice!

    Nice set up but...

    That's not much perimeter insulation. Looks like sill sealer they use on a foundation before they put the wood sill plate down. Maybe an r1 which is 100% more than r0.  I think its there for slab expansion more than anything.  It is a nice setup though, and better perimeter insulation can be easily Incorporated with that system.

    perimeter insulation

    I know it's not much, but it would be leagues better than the 1/2" donnaconna most builders around here insist on using, I did see another similar thing that looked to be more like 1/2" foam. I've been trying to get a builder I work with regularly to do undercut footings under exterior bottom plates to accommodate 2" styro but it's an uphill battle. If I could find something thin with a high R-value that we could put on ourselves it would be an easy solution for now.

    Maybe foam baseboard products?

    I wonder if foam baseboard products would work? It is denser than other foams. Just a suggestion
