Thank you for reaching out. That is not an approved application for QuietWalk Plus.

Thank you for reaching out. In theory this would work, but we have not done any testing in an application such as this to know for certain how it would respond.

Thank you for reaching out. This is not an intended use of the product and we don’t have any testing data to determine if it works or not. However, there is nothing about this application that concerns us. It should help dampen some of the noise being transmitted to the room below.

Thank you for reaching out. The only difference is the film. The film on QuietWalk Plus is designed to accept nails and adhesives so it works under floating floors, nail down floors, and glue down floors. The standard QuietWalk is for floating floors only.

Thank you for reaching out. You will need to perform a calcium chloride test on the concrete slab to determine the emission rate. If the emission rate is less than 7lbs/1000sf/24hrs, then you do not need an additional vapor barrier.

Thank you for reaching out. Those are not approved applications.

Thank you for reaching out. Yes, the QuietWalk is approved for use with radiant heat.

Thank you for reaching out. Standard QuietWalk is not approved to be used under any thickness vinyl plank. The product you will want to use is QuietWalk Luxury Vinyl. https://www.homedepot.com/p/QuietWalk-100-sq-ft-x-3-ft-x-33-34-ft-x-1-4mm-Acoustical-Underlayment-with-Vapor-Barrier-for-All-Vinyl-Plank-Flooring-QWLV100/306837487

Thank you for reaching out. The seams stay together with the factory installed lip and tape system. You need to check with your flooring manufacturer for approved substrates and check if they allow for tile. As for approved floor coverings, this product is approved for use with laminate and floating hardwood.

Like Walking on a Cloud!

[This review was collected as part of a promotion.] We recently ripped up the existing carpet in my upstairs guest bedroom & decided to use this roll of underlayment to pad the subfloor befor installing brand new laminate. I can easily say this was one of our best purchases since beginning our little remodeling journey! The laminate we decided to install wasn’t the highest quality, but this padding brought it to the next level. You can definitely tell the difference between the soundproofing in this room compared to the others in our house. It also gie more support if you’re someone who likes to go barefoot. Would definitely recommend!

Good Quality, Fast Shipping

Also wanted to note that the shipping was great. We’ve bought twice from the same distributor and projected arrival was 10-14 days later but both times they’ve arrived with in 3 days and that was SOOOO helpful!!! Thanks so much for the great service!

Quietwalk Plus

[This review was collected as part of a promotion.] The quietwalk plus floor underlayment allowed us to add an extra layer to our floors before vinyl planks were added. This provides an extra layer to your floors to deter any noise or squeaking when walking on the floor.
