R value for rubber?

who was thinking about putting 2" think solid rubber around his slab on grade building. (It's old rubber track from crawler tractors) As you know, it's hard to insulate the slab edge. Foam won't last outside exposed to sun and everything.
Maybe foam behind the rubber? What would rubber do by itself? Thanks, Kevin

    Skirts

    They make a skirting which protects the perimeter foam from the elements. Old rubber tracks or conveyer belt can't be much r-value 2 max. Let alone easy to work with,or attractive. Don't skimp!

    There's a wide variety of "rubbers"...

    "Dense rubber flooring" has an R-value of about 1.3 per inch.

    "Recycled rubber flooring" has an R-value of about 2.2 per inch.

    And Expanded Rubber

    (aka Armaflex types) between 3.25 and 3.75. I would use the dense rubber flooring number Mike gave for tire-grade stuff. I suppose if you use enough of it, it is a form of recycling. At worst it makes a decent expansion joint. :)

    insulation

    You could try to get the R value by first getting the U value using one sqf of that rubber. I am not exactly sure how you should design it but you could build a box use the rubber and then get your delta T for the u value and then get you R valve.

    Where do you find the skirting?

    I don't know of any good product commercially available. Thanks, Kevin
