Question 2

Would this product work to block bass sound coming from below? My neighbor below plays music at all times, and regardless of years of complaints the sound never stops. I am adding 1/2" pressed felt floor pads and 3"inch floor rugs to all my rooms. Would adding this on top of wood floors, below the felt padding add additional sound absorption? I was considering this product or cork. Thanks! View answer

Question 4

I have a home in Central OR (low relative humidity but cold winters) and want to install a floating click floor. What would be the best underlayment? This looks good, but so does Global MP quietwalk and also the other underlayment you offer with vapor barrier attached. How do I decide? View answer

Question 5

On the sample for Moisture Block it says "It is recommended to also install a moisture resistant film over concrete or any substrate where moisture is a concern."
