Question 11

Plan to install travertine flooring. Per industry recommendations, will use two layers of 3/4" subfloor (not glued together) to get a stiff floor section. However, we are concerned such a stiff floor will be 'hard' to walk on, day in, day out. Would cork add some 'give' back to this floor if applied on top of the two layers of 3/4 subflooring? View answer

Question 12

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

Question 22

Should we use a vapor barrier along with the cork underlayment when installing Wood Wise over concrete? For our current basement remodel, we are seriously considering the Wood Wise flooring option by Amorim. This will be going over a concrete floor (still need to conduct a moisture test). The manufacturer states only a 6 or 8 mil vapor barrier is required as an underlayment, but we won't void the warranty with a 2 mm cork underlayment. Since this project is over concrete, should we install a vapor barrier in addition to the cork underlayment. View answer
