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), featuring a surface metallized gold film coating. This combination provides excellent thermal insulation, moisture resistance, and sound reduction properties suitable for a range of flooring types.
Q
What types of flooring is this EVA underlayment compatible with?
This underlayment is suitable for use with Laminate, Hardwood, Bamboo, and Vinyl flooring. Its flexible structure and stable density make it a versatile choice across multiple flooring applications.
Q
How does the gold film help with moisture management?
The metallized gold film coating on the surface acts as a thermal reflective barrier. It reflects cold temperatures from the ground, reducing the temperature differential between the upper and lower surfaces of the underlayment. This actively inhibits condensation formation, going beyond simple moisture blocking to provide proactive moisture management.
Q
What are the IIC and STC sound ratings for this underlayment?
The EVA 30-G model achieves an IIC (Impact Insulation Class) rating of 73dB and an STC (Sound Transmission Class) rating of 72dB, making it highly effective at reducing both impact noise and airborne sound transmission between floors.
Q
What container load quantities are available for bulk orders?
For bulk shipping, 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). The product is available packaged as nude, on pallets, or in cartons.
Q
What is the thermal insulation value and water absorption rate of this product?
The underlayment has a thermal insulation value of 0.04 W/mK, providing effective temperature regulation underfoot. Its water absorption rate is less than 0.1%, ensuring long-term resistance to moisture penetration and maintaining structural integrity over time.
