Flooring Underlayment Description
Multiply 3/8" plywood flooring underlayment is specifically designed
for use under ceramic tile floors when 3/8 inch plywood is an approved
flooring underlayment. The 7 ply construction makes the panel stronger,
harder and more deflection resistant than typical 3 ply 3/8 inch
softwood plywood flooring underlayment panels. The exterior grade
phenolic glue provides the extra water resistance required for use
under ceramic tiles in non-immersion applications.
The heavy duty 3/8" flooring underlayment panel is also recommended
for use when installing vinyl floors over existing cushioned vinyl
floors. The extra thickness and stiffness of the 3/8" panel eliminates
vertical movement at the seams due to compression of the old cushioned
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 Multiply 3/8"
plywood flooring underlayment in these areas instead of using double
layers of thinner underlayment.
Multiply 3/8" plywood flooring underlayment is not recommended for
exterior use, directly over concrete floors, in showers or similar
high moisture areas, or on any wood subfloor that has a deflection
rating of over L/360 of the span.
Multiply 3/8" plywood flooring underlayment meets the requirements
of the Tile Council of America and other specifying organizations
for use anywhere 3/8 inch plywood flooring underlayment is approved.
All Multiply flooring underlayment panels come with a LIFETIME warranty
against staining and manufacturing defects such as core voids, delamination,
