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
Q
What is the 3mm EVA Underlayment with Gold Film made of?
The underlayment is made of Polyethylene (EVA) material and features a surface metallized (gold film) coating that provides enhanced thermal reflection and moisture management properties.
Q
What types of flooring is this EVA underlayment compatible with?
This underlayment is suitable for use under Laminate, Hardwood, Bamboo, and Vinyl flooring, making it a versatile choice for a wide range of residential and commercial flooring installations.
Q
How does the gold film coating help with moisture control?
The gold film (metallized) coating acts as a thermal reflective layer that reflects cold temperatures from the ground, reducing the temperature difference between the top and bottom surfaces of the underlayment. This effectively inhibits condensation formation, providing proactive moisture management rather than simple passive moisture blocking.
Q
What are the IIC and STC sound ratings for this underlayment?
The 3mm EVA Underlayment with Gold Film achieves an IIC (Impact Insulation Class) rating of 73dB and an STC (Sound Transmission Class) rating of 72dB, providing excellent sound insulation performance for both impact noise and airborne sound.
Q
What roll sizes and container load quantities are available?
The underlayment is available in roll sizes of 100 sq.ft and 200 sq.ft. For container shipping, a 20GP container holds approximately 8,000 sqm (86,000 sq.ft), while a 40HC container can accommodate up to 18,000 sqm (195,000 sq.ft).
Q
What packaging options are available for this product?
The 3mm EVA Underlayment with Gold Film is available in three packaging options: Nude (unpackaged), Pallet, and Carton. This flexibility allows customers to choose the most suitable packaging based on their storage, transportation, and project requirements.
