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 model number and thickness of this EVA underlayment?
The model is EVA 30-G with a thickness of 3mm. It is made from Polyethylene and features a gold metallized film coating on the surface for enhanced moisture and thermal management.
Q
What types of flooring is this 3mm EVA underlayment compatible with?
This underlayment is suitable for use with Laminate, Hardwood, Bamboo, and Vinyl flooring, making it a versatile choice for a wide range of residential and commercial flooring installations.
Q
What are the IIC and STC sound ratings for this underlayment?
The EVA 30-G achieves an IIC rating of 73dB and an STC rating of 72dB, providing excellent impact and airborne sound insulation to create quieter, more comfortable living spaces.
Q
How does the gold film on this EVA underlayment help with moisture control?
The metallized gold film coating acts as a thermal reflective layer that reflects cold temperatures from the subfloor, reducing the temperature differential between the top and bottom surfaces. This actively prevents condensation from forming beneath the underlay, offering proactive moisture management rather than just passive moisture blocking.
Q
What container load quantities are available for bulk orders?
For bulk shipping, the EVA 30-G can be loaded at 8,000 sqm (86,000 sq.ft) per 20GP container and 18,000 sqm (195,000 sq.ft) per 40HC container, making it highly efficient for large-scale distribution and international orders.
Q
What packaging options are available for this product?
The 3mm EVA Underlayment with Gold Film is available in three packaging options: Nude (roll only), Pallet, or Carton. Roll sizes are available in 100 sq.ft and 200 sq.ft to accommodate different project sizes and storage requirements.
