Minor cutting is allowed, but cutting will expose the unprinted edge.

Our UV ink features anti-ultraviolet performance to slow fading indoors.

MOQ starts from 1 piece for sample, bulk order MOQ negotiable. Our UV ink features anti-ultraviolet performance to slow fading indoors.

Yes, we support seamless splicing for large wall artwork.

Yes, we support mixed batch customization according to the project list for EPC projects or large-scale projects. For example, 12mm dark gray (NRC≥0.90) can be used for the main walls, and 9mm light color (NRC≥0.80) for the ceiling. We can split the materials into different pallets and affix corresponding area labels to the outer boxes (e.g., Area A - Dark Gray - 12mm), greatly facilitating your site-specific management and material requisition. The above 60+20 FAQs constitute a very comprehensive knowledge base. If you are doing this for website SEO (Search Engine Optimization), we suggest creating separate topic pages for these Q&As categorized (e.g., "Acoustic Knowledge," "Installation Guide," "Export Certification"), which will make it easier for customers to find what they need. If you need other specific areas (such as in-depth Q&As specifically for home theater enthusiasts, or details of on-site carpentry construction instructions), please let me know, and I will supplement them for you!

It's true that over-absorbing sound can make a room sound "dry." Acoustic design emphasizes a combination of sound absorption and diffusion. Solutions: Don't cover all walls; leave 30%~50% of hard reflective surfaces (such as drywall, glass, or untreated solid walls) untouched. Use an "intermittent" installation (such as a checkerboard layout) and install quadratic residual diffusers (QRDs) in specific locations to achieve both clear and immersive sound.

Not necessarily. The key to sound absorption lies in the material's flow resistance, porosity, and the cavity behind it, not simply the surface design. Surface grooves or embossing (such as wide or thin stripes) primarily enhance diffuse reflection and slightly increase the effective sound-absorbing surface area, but the improvement in the sound absorption coefficient is usually within 5%-10%. Don't just look at the appearance; pay attention to the NRC value measured using the reverberation chamber method.

Because they simultaneously meet three essential needs of early childhood education settings: Absolute Safety: 100% free of fiberglass and asbestos, preventing skin irritation or inhalation into children's respiratory tract. Collision and Cushioning: Flexible and elastic texture, providing some protection against bumps and knocks (superior to hard wood veneer or plasterboard). Acoustic Environment: Reduces classroom reverberation, ensuring clear speech for teachers and protecting children's still-developing auditory systems.

It's recommended to choose flat panels with a melamine finish or a high-density polished surface to minimize exposed pores in catering spaces. Even if they get lightly stained with oil, they can be wiped clean with a neutral degreaser and a damp cloth. However, please note: it's not recommended to install them directly above the kitchen exhaust vent, as prolonged high temperatures will cause grease molecules to seep into the interior and become difficult to clean. It's advisable to install a grease trap before proceeding with the installation.

Yes. The biggest challenge in open-plan offices is speech intelligibility interference. Covering key areas of the ceiling and walls with polyester fiber sound-absorbing panels can effectively reduce ambient background noise by 5-10 dB and lower the speech interference level (LPR) by one level, reducing the number of times employees are distracted by noise. Real-world testing shows an improvement in cognitive focus of approximately 15%.

Our factory implements a strict batch control process: Color difference: Each color adjustment uses a spectrophotometer (ΔE < 1.0 color difference value control), and a standard color sample is retained for comparison. Thickness: We use an online laser thickness gauge for real-time monitoring to ensure that thickness tolerance is strictly controlled within ±0.3mm, far exceeding the industry standard (JC/T 2704-2022 requires ±0.5mm).

The Chinese national standard B1 (GB 8624) classifies materials as flame-retardant. In the North American ASTM E84 test, a flame spread index (FSI) ≤25 and a smoke index (SDI) ≤450 constitute Class A (the highest level), and high-quality flame-retardant polyester fiberboard can reach this level. The British BS 476 Part 7 corresponds to Class 1. If the customer has specific export requirements, please inform us of the target country when requesting a quote, and we can adjust the flame-retardant formula for testing according to specific standards.
