Beyond Barrier: The Proactive Approach to Moisture Management
When ground moisture quietly appears in the form of condensation, traditional barrier-type underlays are often powerless—they can block liquid water but cannot resolve the water droplets formed on the back of the underlay due to temperature differences. These hidden moisture deposits become potential threats to floor health.
The development of the gold film EVA underlay is precisely to address this core challenge. Its surface metallized coating acts like a precision thermal guide mirror, whose core function is to reflect low temperatures from the ground, effectively reducing the temperature difference between the upper and lower surfaces of the underlay, thereby fundamentally inhibiting the conditions for condensation formation and elevating moisture control from "passive isolation" to "active intervention."
