Product Description

Rock Wool Type A High Sound Reduction Wall Panel


Product Introduction:

The Type A High Sound Reduction Wall Panel is a premium acoustic solution engineered to deliver exceptional airborne and impact noise attenuation in demanding environments such as marine vessels, recording studios, theaters, hospitals, hotels, and luxury residential buildings. Designed with a double-steel-facer construction (Type A configuration) and a high-density acoustic core, this panel significantly reduces sound transmission while providing structural rigidity and fire resistance.

Acoustic Performance:

The panel achieves outstanding sound insulation with a weighted sound reduction index (Rw) of up to 45–52 dB, depending on thickness and core material. This performance effectively blocks conversations, machinery noise, traffic sound, and entertainment system bleed-through, creating quiet, private spaces even in noisy surroundings. Independent laboratory tests confirm compliance with ISO 10140 and ASTM E90 standards.


Core Material Options:

To achieve high sound reduction, the panel utilizes one of the following high-density core materials:

*High-density rock wool (120–180 kg/m³) – Excellent for both sound absorption and fire resistance

*Viscoelastic acoustic foam – Superior vibration damping

*Mass-loaded vinyl (MLV) composite – Thin yet heavy barrier

*Mineral fiber board – Balanced acoustic and thermal performance

All core materials are non-combustible or flame-retardant, ensuring safety without compromising acoustic goals.
