    Is there any way to insulate a slab perimeter where the drivway

    meets the slab?

    There was a threshold or cover

    in a similar thread some time ago, maybe the past 3-4 months, describing a product to cover the insulation joint. Yes, there is something.

    Radiant barrier

    Yes two inches of foam. I helped a friend of mine poor concrete in a radiant heated garage. Garage floor was heated and seperated from concrete drive way with two inches of foam set 3/8" lower then finished floor height.We then put a plastic cover on top (an inverted Channel made of plastic) and caulked over it after cure time was up for concrete. Has had to re caulk after two years but holds up nicely.

    I used 2 inch foam

    but cut it at an angle so that It tapered down to a half inch at the very top.so it basically went from 2 inches to a half inch, in about three inches. as that was as deep as my table saw would reach I stood the piece on edge to get the angle, otherwise 45 would have been as steep as I could go.

    Don't leave a raw foam edge, however

    sunlight, gas, oil, dogs, etc will make that disapper then you risk a freeze thaw slab lifting and cracking problem.

    Here is what I have used. The plastic strip caps and protects the foam joint during the pour. Afterwads the top of the plastic protector peels away and a heavy duty butyl rubber caulk, available in colors :) can be added to get a water proof, flexible finish.

    I've not seen a wider version however. I'm sure they could be stacked together for a better R. Any thermal break is better then nothing.

    Take a piece of 2" PVC or ABS pipe and run it through a table saw to make a nice wide cap for 2" foam. Butyl caulk both sided for a seal.

    I think that was me back then asking that question. One reply mentioned http://www.greenstreak.com/Div3/concrete/zipcap.asp
    I spoke with my builder and we decided to stop the 2" an inch or so down, then use a filler board made of PVC (that Azec stuff, or similar) to act as a threshhold (just to hise the ugly foam that would get destroyed). Little to no conductive nature.
