Is Cork underlayment the best for a floating engineered floor project?
Hi everyone, I have not seen this question specifically answered.
I plan on installing 1/2 inch Thomasville engineered wood flooring over a concrete slab (Florida home) on grade.
I plan on floating it. I really want the floor to sound and feel tight and firm when walked on. After laying the vapor barrier, what should I use for the underlayment. Would 6mm cork underlayment be what I am looking for or is there another product out there (hopefully cheaper) that is a better sound suppressor and feels tight when walked on? I don't think I can afford an 8mm or 12 mm cork underlayment.
I guess another way of asking this question is what is the best specific underlayment for an engineered floor. Does the thickness of the engineered floor determine whether cork or some other product would work best? I seen engineered floors in office buildings that were real tight and firm but I assume they were at least 3/4 inch and probably were glued down. I would love to hear your thoughts on this.
Cork is a very good sound barrier in this case. The thicker the laminate in question the better it will sound on it's own so you may be able to use a lesser padding. I'd look into at least a 14lb density. We use Silencer a lot. http://www.foamproducts.com/silencer_main.shtml
It's rubberized and has excellent dampening qualities. The High Density type is what you would probably want.
