UL 9mm (3/8”) Premium Underlayment

9mm plywood underlayment is specifically designed for use under ceramic tile floors when 3/8 inch plywood is an approved underlayment. The 7 ply construction makes the panel stronger, harder and more deflection resistant than typical 3-ply 3/8 inch softwood plywood panels. The exterior grade phenolic glue provides the extra water resistance required for use under ceramic tiles in non-immersion applications.

When new vinyl floors are being installed after old ceramic, wood, or laminate floors have been removed, a height difference is created where the new vinyl meets cabinets or doorways. Use UL48 9mm plywood underlayment in these areas instead of using double layers of thinner underlayment.

UL9mm plywood underlayment meets the requirements of the Tile Council of America and other specifying organizations for use anywhere 3/8 inch plywood is approved.
