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.
★ Key Innovation: 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?
This product is model EVA 30-G, with a thickness of 3mm. It is made from Polyethylene and is designed to provide reliable cushioning and thermal insulation under various flooring types.
Q
What types of flooring is this 3mm EVA underlayment compatible with?
The 3mm EVA underlayment with gold film is suitable for use with laminate, hardwood, bamboo, and vinyl flooring, making it a versatile solution for a wide range of residential and commercial flooring installations.
Q
What are the IIC and STC sound ratings of this underlayment?
This underlayment achieves an IIC rating of 73dB and an STC rating of 72dB, providing excellent impact and airborne sound insulation—ideal for multi-story buildings or noise-sensitive environments.
Q
How does the gold film help with moisture and condensation control?
The gold film (metallized coating) on the surface of the underlayment acts as a thermal reflective layer. It reflects cold temperatures from the subfloor, reducing the temperature differential between the top and bottom surfaces of the underlayment. This proactively inhibits condensation formation rather than simply blocking liquid water, offering a more advanced moisture management solution.
Q
What container load quantities are available for bulk orders?
For bulk shipping, a 20GP container holds approximately 8,000 sqm (86,000 sq.ft), while a 40HC container holds approximately 18,000 sqm (195,000 sq.ft). This makes it highly efficient for large-scale flooring projects and wholesale distribution.
Q
What packaging options are available for this EVA underlayment?
The 3mm EVA underlayment with gold film is available in three packaging options: Nude (unpackaged roll), Pallet, or Carton. Customers can choose the most suitable packaging based on their storage, shipping, and handling requirements.
