Vapor barriers... tyvex vs. tarpaper vs. ???

Well, since I finally painted my floor this evening, I'm now hoping to start actual CONstruction instead of DEstruction.
This weekend I'd like to put down a vapor barrier, then insulation board, then plywood. Somewhere in that mix, I'd also like to put a radiant barrier. Probably this stuff: Reflectix 4' x 25' Double Reflective Foil Insulation

What are the pros & cons of the following?
  • Tyvex house wrap[/*:m:38cpfd87]
  • Roofing Tar Paper[/*:m:38cpfd87]
  • 6mil Plastic Sheeting[/*:m:38cpfd87]
  • pond liner[/*:m:38cpfd87]
The "orange" and "blue" DIY stores sell the first three, and the local plant nursery sells the last one. I haven't done a cost comparison yet, but am looking for some of the best options.

Ooo! And lookie what I found while doing a search for "radiant" :P

Watts SunTouch - 10' x 30" Radiant Floor Warming Mat (120V) for $243.
Still expensive, but maybe worth it!

In my opinion, tar paper will stink, and continue to stink every time it gets heated.

If you enjoy the smell of tar, then I'd say go for it.

hope this helps,

That mat that you just posted seems a better deal than the last one you posted from Northern Tool or Harbor Freight. I really, really like the radiant floor heat idea. I'm still thinking about doing it with water when the time comes, but it's a big $$$$ investment and 120v unit that's 10'x30' would be great for down the road (genny or inverter power) or shore power. I'm glad you ran across that!
