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 flooring types is the 3mm Gold Film EVA Underlayment compatible with?
This underlayment is designed for use with laminate, hardwood, bamboo, and vinyl flooring, making it a versatile choice for a wide range of residential and commercial flooring installations.
How does the gold film help with moisture control?
The metallized gold film coating acts as a thermal reflective layer that reflects cold temperatures from the subfloor. This reduces the temperature differential between the top and bottom surfaces of the underlayment, which significantly inhibits condensation formation — addressing moisture at the source rather than just blocking it.
What are the IIC and STC ratings of this underlayment?
The EVA 30-G achieves an IIC (Impact Insulation Class) rating of 73dB and an STC (Sound Transmission Class) rating of 72dB, delivering excellent sound reduction performance for both impact noise and airborne sound transmission.
What is the water absorption rate of this product?
The water absorption rate is less than 0.1%, meaning the underlayment is highly resistant to moisture absorption, helping to protect your flooring from water-related damage over time.
What roll sizes are available and how much can be loaded per container?
The underlayment is available in 100 sq.ft and 200 sq.ft roll sizes. A 20GP container can hold approximately 8,000 sqm (86,000 sq.ft), while a 40HC container accommodates up to 18,000 sqm (195,000 sq.ft).
What packaging options are available for this underlayment?
The 3mm Gold Film EVA Underlayment is available in three packaging options: nude (unpackaged), pallet, and carton — providing flexibility to suit different shipping, storage, and retail requirements.
