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."
Frequently Asked Questions
What is the 3mm EVA Underlayment with Gold Film made of?
The underlayment is made of Polyethylene (EVA). Its surface features a metallized gold film coating designed to reflect ground-level cold temperatures and reduce condensation beneath the flooring.
What types of flooring is this EVA underlayment compatible with?
This product is suitable for use with laminate, hardwood, bamboo, and vinyl flooring installations, making it a versatile solution for a wide range of flooring projects.
How does the gold film help with moisture control?
The metallized gold film coating acts as a thermal reflective barrier. It reflects cold temperatures from the subfloor, reducing the temperature difference between the top and bottom surfaces of the underlay—thereby preventing condensation from forming and shifting moisture management from passive isolation to active intervention.
What are the sound insulation ratings for this underlayment?
The 3mm EVA Underlayment (Model EVA 30-G) achieves an IIC Rating of 73dB and an STC Rating of 72dB, providing excellent impact and airborne sound reduction for residential and commercial flooring applications.
What container load quantities are available for bulk orders?
For bulk shipping, a 20GP container can accommodate 8,000 sqm (approximately 86,000 sq.ft), while a 40HC container can hold up to 18,000 sqm (approximately 195,000 sq.ft).
What packaging options are available for this product?
The 3mm EVA Underlayment with Gold Film is available in three packaging options: Nude (unpackaged), Pallet, or Carton, allowing flexibility depending on your storage and shipping requirements.
