Acoustic Sandwich Panels utilize a high-performance "Rigid-Soft-Rigid" constrained-layer damping structure. Composed of rigid outer facings (fiber cement, MgO, or galvanized steel) bonded to a viscoelastic damping core, this panel converts acoustic energy into thermal energy, providing exceptional airborne sound isolation and vibration damping.
l High Sound Isolation (38–52 dB): Suppresses panel resonance and sound leakage, blocking low-frequency and high-penetration noise.
l Superior Structural Integrity: High-pressure lamination prevents delamination, providing self-supporting structural wall strength.
l Multi-Level Safety Protection: Offers up to Class A incombustibility alongside moisture, weather, and corrosion resistance.
l Multi-Functional Integration: Combines acoustic insulation, thermal insulation, and dampening for complex industrial conditions.
l Engineered Customization: Customizable dimensions, thicknesses, cores, and facings for tailored engineering needs.
