Soundproof SPC flooring is designed to improve acoustic comfort in environments where noise control is essential. By integrating acoustic underlayment layers such as IXPE, EVA, or cork, this type of SPC flooring effectively absorbs impact sound and reduces airborne noise transmission between floors. It significantly lowers footstep noise, chair movement sound, and vibration, creating a quieter indoor environment. Soundproof SPC flooring is widely used in offices, hotels, apartments, libraries, conference rooms, and healthcare facilities where acoustic performance directly affects user experience. In addition to sound insulation, it maintains excellent waterproof performance, surface durability, and structural stability, making it a multifunctional flooring solution that balances comfort, performance, and long-term reliability.
