What mil thickness of underlayment is best to use for wood laminate flooring to reduce moisture and noise?

Question

I am working with a plywood subfloor. If your home improvement store does not have many options available for underlayment in stock, can you put 2 layers of thinner (1mm) underlayment to improve noise reduction and insulation? Also, is it better to buy flooring with underlayment attached or is buying quality underlayment just as effective?

Answer 1

3 to 5 mil thickness is recomended

Answer 2

the thicker the mill the better it will be with sound barrier and moisture from sub floor i wouldn't recommend doubling the underpayment there is also a foam underlayment and a rubber type and also a fabric type underlayment made by silent step and quite walk out of choose i would go with the rubber compound or the cloth type just make sure u tape ur seams personally if i was laying laminate in my house i would use a cork underlayment and lay plastic underneath the cork for the moisture barrier u can find some of thoose products on online floor suppliers ifloor.com is resionable

Answer 3

it will say on the box what you should use. you can buy laminate with the underlayment attached already. used it in my

kitchen, worked great.
