Product Q&A

Q:Do you provide free samples?

Yes, free small samples (A4 size or 1m long roll) are available. Generally, the buyer only needs to bear the courier cost. Customized thickness or composite samples may require a small additional fee.

Q:Are your product dimensions fixed?

No. The standard width is fixed at 1200mm, while the length can be customized according to project requirements (e.g., 10m/20m rolls). Custom thicknesses (beyond 1.2/2/3mm) are also available.

Q:What are your payment terms?

We accept T/T, L/C, D/P, and Western Union. For standard orders, full payment is required before shipment; for bulk projects, a 30% deposit + 70% balance before delivery is also negotiable.

Q:What is the main function of this sound insulation felt?

It works by combining high mass density with damping performance, effectively blocking airborne noise (speech, traffic) and reducing structure-borne vibration/impact noise, especially at mid-low frequencies.

Q:How do I choose the right thickness?

1.2mm (23dB): For light noise reduction, partition walls, ceilings. 2.0mm (27-29dB): For home theaters, KTV, bedrooms. 3.0mm (30-32dB): For industrial equipment, pipes, and high-noise environments.
