High-Efficiency Thermal Reflection Barrier
The core structure of this product consists of a 2mm IXPE foam substrate laminated with a specialized aluminum foil layer — a design that is far from merely decorative. The primary function of the aluminum foil layer is to form a highly efficient thermal reflection barrier.
When radiant heat is generated by heat sources (such as underfloor heating pipes, automobile engines, or rooftop solar radiation), the aluminum foil layer acts like a mirror, reflecting the vast majority of thermal energy directly back, thereby significantly blocking the one-way transfer and dissipation of heat. Unlike ordinary aluminized films, the high-density aluminum foil used in this product features more complete metallic continuity. Even after long-term use or slight bending, its reflective performance remains durable and stable without noticeable degradation. This physical reflection principle fundamentally enhances the overall thermal insulation performance of the material.
Frequently Asked Questions
Q1
What is IXPE foam and how does it differ from standard PE foam?
IXPE (Irradiation Cross-Linked Polyethylene) foam is produced through an electron beam irradiation process that creates a cross-linked molecular structure. Compared to standard PE foam, IXPE offers superior density uniformity, better compressive strength, improved thermal insulation, and a smoother cell structure — making it ideal for use as a high-performance flooring underlayment.
Q2
What types of flooring is this 2mm IXPE underlayment compatible with?
This product is suitable for a wide range of flooring types, including laminate flooring, solid hardwood, engineered hardwood, and bamboo flooring. Its thin 2mm profile makes it especially well-suited for floating floor installations where height clearance is a consideration.
Q3
What do the IIC 61dB and STC 64dB ratings mean for everyday use?
IIC (Impact Insulation Class) measures how well a floor assembly reduces impact noise such as footsteps — a rating of 61dB indicates excellent impact sound reduction. STC (Sound Transmission Class) measures airborne sound reduction; 64dB is a high-performance rating. Together, these ratings mean this underlayment significantly reduces both footstep noise and room-to-room sound transmission.
Q4
How does the aluminum foil layer enhance thermal insulation performance?
The aluminum foil layer acts as a radiant heat reflector. When heat energy radiates from sources such as underfloor heating systems or solar radiation, the foil reflects the majority of that energy back rather than allowing it to pass through. The high-density aluminum foil used maintains its metallic continuity even after bending or extended use, ensuring long-term and stable thermal reflection performance.
Q5
What is the water absorption rate, and why does it matter?
This product has a water absorption rate of less than 0.1%, which is extremely low. This means the underlayment will not absorb moisture from the subfloor, helping to prevent mold, mildew, and structural damage to the flooring above. It also ensures the material maintains its insulation and cushioning properties over time even in humid environments.
Q6
What are the available container load quantities for bulk orders?
For bulk purchasing, a standard 20GP container can accommodate approximately 12,000 sqm (129,000 sq.ft) of product, while a 40HC container can hold up to 27,000 sqm (290,000 sq.ft). This makes it highly efficient for large-scale flooring projects or wholesale distribution. The product is available packaged nude, on pallets, or in cartons depending on shipping requirements.
