Customer Questions

Don't see what you're looking for? 
does your cork or other floors require an adhesive or any additional products. I'm looking at the cork and the sound proofing (foil looking one)?
Jessica Lerda
In most installations the cork underlayment needs to be adhered with a urethane adhesive and a vapor barrier would need to be included. Our Sound Blocker Underlayment can be installed without the need for adhesive to the subfloor but you will need to remember to tape the seams with moisture resistant tape. Always follow installation instructions for any underlayment.
Our installation of 3mm cork is as a sound barrier above grade (3rd floor residential condo), conditioned space below, placed on top of 1" cured gypcrete below and 2 layers of 3/4" Advantech T&G subflooring above the cork with carpet or hardwood as a finish surface. I would not expect this application to require an adhesive or a moisture barrier - Correct?
Joe Sampson
You would not need a moisture barrier, but we do recommend that you glue the cork underlayment down.
Does the vapor barrier go between to flooring and the cork?
Yes, if you are going to put down a vapor barrier but it between your concrete and underlay.
Does the 3mm product have an IIC rating?
This product has not been tested and does not have any ratings available.
Is this quarter-inch and how many sq ft in one roll?
Marvin Rosenfeld
This cork underlay would be equivalent to about a 1/8". The size of our 3mm Eco-Cork Underlayment rolls is 4' x 50', which covers around 200 square feet.
I have a concrete slab floor in a garage and would like to install NuHeat floors and porcelain or Luxury Vinyl floor. Can I use any underlayment product on top of the concrete then lay NuHeat NVent heated mats (with thinset) over the underlayment?
When installing your NuHeat NVent heated mats, you would install them over our 3mm Eco-Cork Underlayment. You would want to follow the instructions for installing the underlayment and installing your heated floor system.
