Answer: 
Jim-
A vapor barrier is not needed. Plywood has to breathe and if the moisture is trapped, it will likely rot the plywood over time. There is no need to add another laminate either. Hope this helps! Please contact us if you have any further questions. Thank you for choosing Roberts!

Customer Reviews

Rated 4.5 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Best value in low price laminate floor padding. The 'giant' size roll underlayment is priced at about 15 cents per square foot. Smaller quantities of the same pad sell for 25 cents psf so the big roll is a significant savings. Light enough for a man or woman to easily pick up and handle the 1500 square foot roll. Has a vapor barrier built in to the top. If you end up with extra left over, it makes a dandy bubble wrap for packing dishes, electronics, etc. May 24, 2016
