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 type of flooring is the 3mm EVA Gold Film Underlayment compatible with?
The 3mm EVA Gold Film Underlayment is suitable for use with laminate, hardwood, bamboo, and vinyl flooring. Its versatile design makes it an ideal solution for a wide range of residential and commercial flooring installations.
Q
How does the gold film coating help with moisture management?
The metallized gold film coating acts as a thermal reflective layer. It reflects cold temperatures from the ground upward, reducing the temperature difference between the upper and lower surfaces of the underlayment. This significantly inhibits condensation formation, providing an active approach to moisture control rather than simply blocking liquid water.
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 packaging options are available and how much can fit in a container?
The product can be packaged nude, on a pallet, or in a carton to suit different shipping and storage requirements. A 20GP container holds approximately 8,000 sqm (86,000 sq.ft), while a 40HC container accommodates up to 18,000 sqm (195,000 sq.ft).
Q
What is the water absorption rate of this EVA underlayment?
The EVA 30-G underlayment has an extremely low water absorption rate of less than 0.1%, ensuring that it maintains structural integrity and performance even in environments with elevated humidity or moisture levels.
Q
What is the thermal insulation value and density of this product?
The underlayment has a thermal insulation value of 0.04 W/mK, helping to maintain floor warmth and reduce energy loss. It has a density of 100 kg/m³ and a thickness of 3mm, providing a firm yet comfortable support layer beneath your flooring.
