Floor Underlayment 3mm, 200 Sq Ft Roll, Tape Vapor Barrier

Floor underlayment with vapor barrier creates a smoother, quieter base for laminate and engineered wood floors while helping block moisture from below. This 3-in-1 3 mm padding combines dense EPE foam for stability and sound reduction with a PE film vapor barrier and pre-applied seam tape for faster installs. One roll covers 200 sq. ft, making it a practical choice for larger rooms where you want fewer seams, less waste, and a clean, consistent underfloor surface.

Upgrade your install with underlayment that supports your floor and your schedule. The heavy-duty EPE foam layer helps keep planks feeling stable underfoot, while the moisture-resistant film adds everyday protection in basements and ground-level rooms. With generous roll coverage and easy cut-to-fit handling, you can prep large areas faster and with fewer interruptions.
