What is it…exactly?
IXPE is a premium acoustical underlayment made up of sound dampening high-performance cross-linked foam with an overlapping film for extra moisture protection at its joints. The extra fine foam offers advanced moisture protections and shock absorption. Utilizing the Progressive Foam Technology (PFT), IXPE underlay is designed for supreme sound Reduction.
Its Closed Cell, why is that Important?
Closed cell is how it sounds. The membrane of it is made of cells that are impervious to absorption. This means that water,fungus,bacteria and other estructive forces can invade your floors from the bottom and are blocked out.
