Beyond Barrier: The Proactive Approach to Moisture Management
⚠Traditional barrier-type underlays can block liquid water but cannot resolve condensation formed on the back of the underlay due to temperature differences — these hidden moisture deposits become potential threats to floor health.
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
Q1
What is the 3mm EVA Underlayment with Gold Film made of?
The underlayment is made of Polyethylene (EVA) foam with a surface metallized gold film coating. The gold film layer acts as a thermal reflective barrier to help manage moisture and temperature differences between floor surfaces.
Q2
What types of flooring is this EVA underlayment compatible with?
This underlayment is suitable for use with Laminate, Hardwood, Bamboo, and Vinyl flooring. It provides thermal insulation, sound reduction, and moisture management benefits across all these flooring types.
Q3
What are the IIC and STC ratings of the EVA 30-G 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.
Q4
How does the gold film coating help with moisture management?
The metallized gold film coating on the surface of the underlayment reflects cold temperatures from the ground, reducing the temperature differential between the upper and lower surfaces. This proactively inhibits condensation formation — going beyond simple moisture blocking to actively prevent moisture buildup beneath your floor.
Q5
What are the available roll sizes and how much can fit in a container?
The EVA 30-G underlayment is available in roll sizes of 100 sq.ft and 200 sq.ft. A 20GP container can hold approximately 8,000 sqm (86,000 sq.ft), while a 40HC container can accommodate up to 18,000 sqm (195,000 sq.ft).
Q6
What packaging options are available for the EVA underlayment?
The product is available in three packaging options: Nude (no outer packaging), Pallet, and Carton. These flexible options accommodate different shipping, storage, and retail display requirements for both small and large orders.
