Question 1

I see that taping is an option for this flooring but is it better for the microclimate to not tape it?

Accepted Answer

Hello! Since the underlayment is designed as Water Vapor system, it has an ability to "breathe" no matter if tape is there or not (air is going through all the surface). Tape might be used on joints if desired to fix the Underlay and prevent moving while installing, tape could be used on full length of joints, by small pieces or could be not used at all.

Question 2

I'll be installing this on a concrete slab and want to know if I can use it in a bathroom underneath tile or marble floors?

Accepted Answer

We recommend using our Underlayment under the floating floors. In the bathrooms, you can use it in places where there is no direct water exposure to the finishing surface. Our clients do install STEICO Underlayment under tile but we have not accumulated enough experience yet to recommend using it this way.

Question 3

I need 3mm in addition to the 1/4 inch that the Steico underlayment provides. Can I use a 3mm foam vapor barrier underneath to make up the difference?

Accepted Answer

The thicker the layers, the spongier they get.  The more movement, the less wear.  I think layer them would be a mistake.

Question 4

The 1/th and 1/4inch versions of this list the same delta iic.  how is this possible?  why is thicker better?

Accepted Answer

Dear James, thank you for the great question! 
To be honest, we were also very surprised when we received the results of the testing. We have been explained that during the testing various materials perform differently within different structures. Testings with our products (both 1/8" and 1/4") were done according to the toughest requirements ( 6' concrete slab and no ceiling assembly). Apparently with the wood fiber materials and in this particular setting, it does not make a significant difference for the soundproofing which thickness do you select ( 1/8" or 1/4"). 
Thicker wood fiber underlayment is commonly used when the elevation of height is needed or the subfloor is uneven.
We hope it help!
