Fact Sheet

Published / Updated:

CertainTeed Platon Sub-Floor Systems are an impermeable damp proof barrier that lifts the floor off the damp, cold concrete. Platon is a strong, double dimpled, 24 mil HDPE membrane that is placed over the concrete flooring. This creates an air gap and nearly impermeable vapor barrier, therefore the concrete can breathe while still keeping the floor dry. The finished floor is then placed on top of the Platon sub-floor and it becomes room temperature, keeping your warm and helps eliminate moisture problems in your flooring.
