I'm doing a floating plywood subfloor over concrete then felt or tar paper then engineered wood nailed to the subfloor. The NWFA suggests a vapor barrier in between the concrete and plywood, will this work? Thanks

For anyone who has used this as a vapor barrier below laminate or hardwood flooring (possibly with underlayment in-between), have you noticed sound from walking on your flooring caused by this VaporBlock (i.e. maybe because the polyethylene wrinkled underneath, it caused sound when walking on it)?
Asked by: Kam
I installed this under laminate and cannot hear anything.

VaporBlock 150 sq. ft. 6 ft. x 25 ft. x 0.006 in. Polyethylene Vapor Barrier Underlayment for Hardwood Laminate Floors is rated 4.5 out of 5 by 14.

I replaced the flooring in one of my basement bedrooms and when I pulled up the old laminate, there was no vapor barrier. I figured as much before I started the redo as the existing laminate flooring was starting to warp a bit on the edges of each piece. It wasn't anything major, but noticeable and an obvious sign of improper installation to begin with. This vapor barrier applies easily enough. The adhesive strip for "easier" overlay does make the overlaying easier, but you do need to be careful and take your time. If you pull the backing off and let the adhesive part touch where you do not want it, you will see that it is tricky pulling it off to re-position. But that's actually a positive if you ask me. It shows me that the tape part is actually good quality and will hold. I would absolutely use this product again and recommend it to others. Just a note - this is purely for vapor, as in a basement floor that is below or on grade. You wouldn't use this for sound or any other application above grade.

The price is right, the product is heavy weight and solid and it works beautifully. What else could you ask for? I used this on a basement floor that is usually pretty dry but sometimes feels a little moist; nothing serious, but still I wanted to protect the engineered bamboo I was using. It worked easily under the floor and I'm sure will protect it for many, many years.

I have done quite a few hardwood laminate floors throughout the years and i would always recommend to put a vapor barrier over the sub floor before installing the laminate. This vaporblock is this and easy to apply and at 25' in length it is super easy to work with. For it being 6 mil it feels more durable than other underlayments i have used in the past

This is a very good quality vapor barrier and a must of any renovation work that you are doing where you are exposing your foundation beams. I am using it in my basement bathroom and the thickness and size is just what I needed. I am using it for a vapor barrier on the framing walls in front of the spray foam and ceiling. All you need is a stable gun and a box cutter. I would recommend this product to a friend and would also purchase this product again. If hung correctly this will prevent drafts from the outside from coming through as well as prevent moisture from seeping through.

This is much thicker, heavy and with good materials. To use as an underlayment for wood floor should be a good vapor barrier. For my purpose it is a good protection because of I have an underlayment without vapor barrier. I am using it with my existing unverlayment to have better sound and vapor protection wood floor.
