Laminate vapor barier underlayment question

amdspitfire

The laminate has pad backing already so all I need is a plastic sheet underlayment. The 6mil sheeting in the hardwood isle is very expensive but comes with a nice strip of tape so you can overlap the layers.

Can I just get a big roll of some 6mil plastic sheeting? Like the black garbage bag material stuff or should I stick to the fancy stuff?

You can use 6 mil Poly.

Tape the edges with Tyvek Tape (House wrap tape).

So this kind of sheeting will be fine?

That's fine.

You could use that or even the "clear"...whichever is more "cost-effective".

Thanks a lot, just trying to make sure this stuff will work instead of spending a bunch of money on the fancy stuff in the flooring isle.
