What is the typical warranty period for polyester fiber sound-absorbing panels?

2026-07-16
Under normal indoor conditions, the product can be used for 5-10 years or more. The specific warranty period varies depending on the manufacturer; it is recommended to confirm the warranty terms with the supplier at the time of purchase. The product material is stable and will not naturally decompose or release harmful substances over time. The above 30 FAQs, combined with the previous 30, total 60 questions, covering the entire process from product basics, performance parameters, installation, maintenance, application scenarios to certification standards, transportation and storage, material comparison, and procurement inspection. Further additions or adjustments can be made based on actual customer feedback.

Related questions
1
How to achieve a flush joint between sound-absorbing panels and other materials (such as wood veneer or hard paneling) on the same wall?
The key lies in the precise control of the base layer thickness. Before installation, based on the total thickness of the polyester fiber sound-absorbing panels (e.g., 12mm) and other materials (e.g., 9mm wood veneer + 3mm underlayment), leveling layers of plywood or framing at different heights should be applied to the wall surface to ensure that the finished surfaces of all materials are on the same horizontal plane. Finally, a T-shaped trim strip should be embedded at the joint for a smooth transition.
2
Will digital printing on sound-absorbing panels affect the sound absorption effect?
The impact is very small. High-quality UV inks or water-based penetrating inks, with a coating thickness of only 0.02-0.05mm, will only seal a very small number of micropores on the very surface, and the impact on the overall noise reduction coefficient (NRC) is negligible (usually a reduction of <0.05). However, it is crucial to avoid using paint for spraying, as paint will seal large areas of pores and severely impair the sound absorption function.
3
Can polyester fiber acoustic panels be customized with wood grain, stone grain, or fabric textures?
Absolutely. Through heat transfer printing or digital UV flatbed printing, any wood grain, stone grain, geometric pattern, or artistic image can be precisely replicated onto the surface of the acoustic panel. The pattern layer is extremely thin, barely affecting the original sound-absorbing porosity. Our factory offers custom design services based on provided images. Please consult our sales manager for the minimum order quantity.

How to prevent glue from overflowing from the seams and staining the board surface during installation?
The "wall-applying glue method" should be strictly used (glue is only applied to the wall substrate), not the back of the board. If glue accidentally spills, immediately wipe it gently with a damp cloth soaked in alcohol or a special cleaner. Do not wait for the glue to dry completely before scratching it off, otherwise it will damage the texture and color of the board surface.
5
Can polyester fiber acoustic panels be used on curved walls or to wrap cylinders?
Absolutely. Polyester fiber acoustic panels are flexible; 9mm thick panels can be safely bent into curves with a radius greater than 300mm, and for 12mm thick panels, a minimum bending radius of 500mm is recommended. During installation, it is recommended to use dry-hanging or keel fixing methods to avoid using rigid adhesives that restrict the bending stress of the panels.
6
How should holes be drilled for sound-absorbing panels if there are switches, sockets, or fire hydrants on the wall?
The safest method is to "install first, then drill the holes." First, use a utility knife or jigsaw to roughly drill holes in the panel that are about 5mm smaller than the actual equipment. After attaching the panel to the wall, use an edge trimmer or fine-toothed saw to precisely trim along the edges of the equipment. If you are drilling the same holes in batches, it is recommended that the factory provide a pre-drilling customization service so that the panels can be directly fitted on-site, greatly improving efficiency and reducing dust.
