Question 2

You mention it "reduces abrasion", is that specified somewhere? Does it allow same level of movement as rosin paper? Manufacturer of OSB in a two layer subfloor layout calls for 15lb felt (prevent squeaking). Doing 1 x 6" wood slats as 1st subfloor layer, then underlayment on top of the 1st subfloor layer (15 lb felt, or equivalent, presumably silicon vapor shield, aka SVS), then a 1 1/8" OSB subfloor layer, which we xxxx down through the underlayment with 1 3/4 inch decking screws. a) Do we staple/nail down silicon vapor shield or loose lay? Maybe underlayment seal tape to cover seams? Or double sided tape to secure to the floor/prevent it from moving as the OSB 4' x 8' sheet is placed on top of it and screwed down to 1st layer subfloor?

Is this cork underlayment suitable beneath a floating engineered hardwood floor? View answer

Asked 9 ´months ago | Natural Cork Underlayment Roll

Question 17

We plan to install floating cork flooring over cement slab at grade. A moisture barrier like Moisture Block is needed as our real-life experience of moisture migrates from the ground up, through cement. We also want QuietWalk: it's insulative, cushioning & moisture wicking. The cork floor manufacturer's installation pdf says don't install the floor over an underlayment more than 1/8" (0.125) thick. QuietWalk is .13" thick (.05" too thick). Plus .006" thick Moisture Block would exceed max allowable thickness by .056. I saw in another Q&A using both may be overkill, but I feel we need both. I'm confused about exceeding the manufacturer's allowed underlayment thickness. Can you clear up any confusion and can I use both underlayments together? View answer

Question 24

Hello, I am installing a click-lock engineered hardwood flooring on top of an existing wood floor. The manufacturer recommended underlayment is a 2-in-1 foam underlayment, max 1/8" thick. A vapor barrier is important here as the level directly below is the cellar (not heated) and there is no subfloor below the existing floor. Do you recommend MP Global, QuietWalk Plus for this situation? Thank you! View answer

I really like the cork underlayment. Our subfloor is plywood over a crawl space so I likely need a vapor barrier. Perhaps I should just stick with Quietwalk? We plan to install floating bamboo on top. View answer

Asked 1 ´year ago

Question 34

We are thinking of purchasing strand bamboo flooring (USFloors Ming) and using this underneath. Do we still need a vapor barrier between the concrete and the cork underlayment or can you forgo the plastic underlayment (just cork and flooring)? We live in Florida, a very humid climate if that is relevant. View answer
