Beyond Barrier: The Proactive Approach to Moisture Management
Key Innovation
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 types of flooring is the 3mm EVA Gold Film Underlayment compatible with?
This underlayment is suitable for use under laminate, hardwood, bamboo, and vinyl flooring, making it a versatile solution for a wide range of residential and commercial flooring installations.
What is the purpose of the gold film coating on this EVA underlayment?
The gold film is a metallized surface coating that functions as a thermal reflective layer. It reflects cold temperatures from the subfloor, reducing the temperature differential between the top and bottom surfaces of the underlayment. This actively prevents condensation from forming on the back of the underlay, providing proactive moisture management rather than simple moisture blocking.
What are the sound insulation ratings for this product?
The EVA 30-G achieves an IIC (Impact Insulation Class) rating of 73dB and an STC (Sound Transmission Class) rating of 72dB, offering excellent sound reduction performance for both impact noise and airborne sound transmission.
What is the water absorption rate of this underlayment?
The water absorption rate is less than 0.1%, meaning this underlayment is highly resistant to moisture absorption. This low rate helps maintain the structural integrity of the product over time even in environments with elevated humidity.
How much product can be loaded per container?
For a standard 20GP container, the load capacity is 8,000sqm (approximately 86,000sq.ft). For a 40HC container, the load capacity increases to 18,000sqm (approximately 195,000sq.ft), making it efficient for large-volume international orders.
What packaging options are available for this EVA underlayment?
The product is available in three packaging options: Nude (unpackaged rolls), Pallet, or Carton. Each roll is available in sizes of 100sq.ft or 200sq.ft, offering flexibility to suit different project scales and logistics requirements.
