This is Ruibin from Hebei Woqin. Many clients ask: 'Why should I choose your glass wool when there are so many options?' My answer is simple: We don't just sell rolls; we solve condensation and noise issues in extreme environments. Whether you are insulating a 450°C steam pipe in a chemical plant or trying to pass a strict acoustics audit for a recording studio, our glass wool is engineered to stay stable. We use high-purity recycled glass, ensuring the fiber diameter is uniform, which is the secret to our NRC ≥0.8 rating.
Technical Specifications (Lab Certified):
Standard Density: 10kg/m³ - 96kg/m³
Thermal Conductivity (25°C): 0.034 W/(m·K) (Excellent Performance)
Fire Resistance: Non-combustible Class A1
Water Repellency: ≥99.2%
NRC (Noise Reduction): 0.85
HVAC Condensation Control: Our glass wool foil-faced wrap is a top choice for Middle Eastern cooling systems. It prevents sweating on cold water pipes even in 90% humidity.
Power Plant Boilers: Specifically designed for high-vibration environments. The fibers don't break down or sag, maintaining their R-value for 10+ years.
Acoustic Engineering: Used in cinema partitions and engine rooms. It doesn't just block heat; it literally 'eats' sound waves.
Don't ignore the binder. Many cheap glass wool products use low-quality binders that emit formaldehyde when heated. Woqin's Formaldehyde-free series uses a bio-based binder, ensuring zero VOCs. If your project is for a hospital or school, do not compromise on this.
Minimum Order Quantity (MOQ): 1x20GP container.
Customization: We provide aluminum foil, kraft paper, or white PVC facing options.
Shipping: Fast loading from Tianjin Port.
Compliance & Standards:
Standardization: Our Glass Wool meets ASTM C547 (for pipes) and EN 13162 (for buildings).
Fiber Safety: Biosoluble fibers, tested to be safe for human contact and environmentally friendly.
Corrosion: Non-corrosive to steel and aluminum pipes (Passed ASTM C665 test).

Ruibin’s Tech Tips (FAQ):
Q: Can I use glass wool for outdoor steam pipes?
A: Yes, but you must use our Aluminum Foil-faced version and ensure a mechanical jacket (like aluminum or stainless steel) is installed to protect against UV and rain.
Q: What is the difference between your 16kg/m³ and 48kg/m³ glass wool?
A: The 48kg version is rigid and offers much better acoustic absorption for engine rooms, while the 16kg is more flexible for wrapping HVAC ducts.
Ruibin's Professional Advice: "If you are unsure about the density needed for your HVAC project, just send me your duct size – I usually respond with a technical recommendation within 10 minutes."
