The reflective surface goes down. If you look carefully, it says it right on the surface!
The dark or black side will say, "THIS SIDE UP."
Hope this helps.

Answer: 
You can face it either way. The rolls are made to roll the reflective surface down. If you are placing any type of radiant heating system on the underlayment I would suggest laying the reflective surface up.

Does this product count as vapor/moisture barrier for under laminate? Do I need to lay a separate moisture barrier? i.e. 6 mil plastic.

Answer: 
The product has dual films attached that serve as a moisture barrier. I recommend doing a moisture test on the subfloor before you start installation. If the readings are below the flooring manufactures established guidelines (typically less than 3 lbs/1000 sqft) you can install without a 6 mil poly.

Hey Grouper,
Since this underlayment acts as its own moisture barrier, buying a sheet of plastic would be unnecessary.
If the flooring and this underlayment would be placed in a below grade (basement) concrete subfloor, then painting a sealer or paint would give yourself a better chance of reducing any chances of moisture coming through.

Since the 3-in-1 underlayment acts as its own moisture barrier, using a separate moisture barrier would be useless.
If this is a concrete, and especially below grade (basement) slab, then you can seal the floor with a paint or primer to assist in preventing moisture seepage from occuring.

Thinking about wood floors in the basement - very cold cement floor (North East).... Which one would be better in terms of value and thermal properties: this or cork subfloor with moisture barrier or Roberts airguard?
Thank you very much for your help.

Answer: 
All the products will provide some insulation. I don't believe there will be a noticeable difference in the 3 products. If you install a radiant heating system between the floor and underlayment I would recommend placing the metalized film up.

Answer: 
Traffic master premium or cork product should help to insulate your basement floor. If you are installing a wood floor please consult with the wood flooring manufacture to verify that it can be used in a basement or below grade installation. Wood floors are very sensitive to moisture so you must prepare the subfloor in a basement for a wood or moisture sensitive product.

Rated 4.7 out of 5 by 55 reviewers.
Rated 5.0 out of 5.0 by Excellent underlayment for the cost. Although any underlayment will work, and I've successfully used the foam types up to my most recent installation, this upgrade is well worth it if your budget can handle it. It goes down easier, your floor will have a more solid feel, and the thermal properties will enhance installations over garages and in basements. September 6, 2016

Rated 4.0 out of 5.0 by Can be a bit noisy The rolls are easy to install and the tape makes for easy seaming. However, the material make crinkly noises when walked on, even underneath 12mm laminate. Play with it in the store and you'll see and hear what I mean. It unfortunately makes the flooring seem chintzy because it makes a crunchy sound with every step. September 12, 2016
