Frequently Asked Questions

Q: What is the NRC rating of your panel, and how is it tested?
A: Our panel achieves an NRC of 0.8, tested according to ASTM C423 standard. This means it absorbs 80% of incident sound energy, making it highly effective for reducing echo and reverberation.
Q: Can I get custom perforation patterns or colors?
A: Yes, we offer extensive customization. You can choose from round, square, or custom patterns, and any RAL or Pantone color. Minimum order quantity may apply for custom designs.
Q: Is the acoustic backing fire-resistant?
A: Our standard backing material is flame-retardant (passes UL94 V-0 or equivalent). If you require a specific fire rating, we can provide a specialized backing at additional cost.
Q: What is the lead time for a standard order?
A: For standard sizes and colors, lead time is typically 15-20 working days after order confirmation. Custom orders may take 25-30 working days. We can expedite for urgent projects upon request.
Q: How do you ensure quality control?
A: We are ISO9001 certified. Each panel undergoes dimensional inspection, perforation density check, color consistency, and acoustic performance verification. We also provide a quality certificate with every shipment.
Q: What is the weight of one panel?
A: A standard 1200x2400mm panel with 1.2mm aluminum weighs approximately 2.8 kg. Actual weight may vary based on perforation pattern and backing type.
Q: Can these panels be used outdoors?
A: While aluminum is corrosion-resistant, the acoustic backing may degrade under direct UV exposure. For outdoor use, we recommend a weather-resistant backing or a protective coating. We can advise on suitable options.
Q: Do you provide installation instructions or accessories?
A: Yes, we provide detailed installation guides and recommend mounting systems (clips, rails, or adhesives). We can also supply matching accessories like trims and fasteners upon request.
