Answer: 
The Bellawood is actually .65 R-Value for the 89 cent (regular price). Also the Bellawood is pre-compressed and antimicrobial. I thought about which to go with and my outcome was Bellawood by far!!

Answer: 
The calculated R Value based on 4.07 per in and a thickness of .093 inches is R = 0.37 and a current cost of 45 cents/foot. Compare with Roberts Airgaurd at R = 0.39 and a cost of 55 cents /foot (or lower if purchased in quantity). Bellwood premium underlayment R = 0.52375 at a cost of 90 cents / foot when on sale. Overall, this seams like a very good value.

Answer: 
The R-Value is 4.07/inch. The other key component of this product is the reflectivity of the metalized film. The high reflectivity of the film will help reduce the effect of radiant energy.

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.

Answer: 
Yes, but the moisture barrier will be destroyed when you put a nail through the product. This type of underlayment is typically used with floors that have a click locking system.

Rated 4.7 out of 5 by 44 reviewers.
Rated 4.0 out of 5.0 by nice underlayment easy to install deadens the sound when walking on the floor April 6, 2016
Rated 5.0 out of 5.0 by Solid Product Easy to install - solid feel - all in one product - price was fair March 15, 2016
Rated 4.0 out of 5.0 by Works great I've used this under my click-lock solid bamboo flooring a couple of times now. It goes down quick with a couple staples to hold it in place. 1 floor has been down for over a year now, and doesn't show any signs of wear. January 19, 2016
Rated 5.0 out of 5.0 by Overly Satisfied This product is amazing! I don't have the 3-1 under the wood in my kitchen and boy can I tell a difference with the temperature and sound. Wishing the previous owners used this under the kitchen floors. January 21, 2016
Rated 5.0 out of 5.0 by Solved a Ton of Problems! I would normally never write a Review, but this time it was so perfect of a product I thought I should say never lay a wood floor without using this product. The first part of my project I used the standard brown/red paper that the instructions said to use, however I noticed walking on the floor it has a clicking noise and the hardwood feels cheap and it wasn't. However after using this product in the bedrooms we have a floor that went together easier, no noise, and feels like we added a extra sub-floor.... This Product made life easier and we feel really good about our new floors.... It's a Must Use. November 23, 2015
Rated 5.0 out of 5.0 by Recommend this product We used this under hardwood floors. Its great. The floor is warm and the underlay keeps the sound down, with dogs thats a big plus. December 15, 2015
Rated 5.0 out of 5.0 by Great Product The underlayment rolled out easy and the taped ends to stick the new roll to was helpful so there was no shifting. October 1, 2014
Rated 5.0 out of 5.0 by No-nonsense underlayment We used this 3 in 1 underlayment to put down 1500 sq ft of laminate flooring. It was very easy to spread, cut around and tape. It was put on after leveling the floor, has provided a sound proof cushion for the12 mm laminate flooring. You can see it under the laminates in the picture below. We never hear any clicking noise. It is a quality product, with a low price. December 10, 2013
