Weight Of Sound-absorbing Panels

The weight of sound-absorbing panels varies significantly due to different materials, specifications and thicknesses. The common range is from 1.4kg/㎡ to 12kg/piece. The specific selection should be based on the type (such as gypsum-based, wood, aluminum fiber, etc.) and purpose.

Weight comparison of different types of sound-absorbing panels

Gypsum-based high-crystal perforated sound-absorbing panels: lightweight and environmentally friendly, weighing 6-8kg per square meter, suitable for wall decoration. FC perforated cement sound-absorbing panels: mainly fiber cement, a single piece (specification 1200*600mm) weighs 12kg, and has outstanding fireproof performance. FC perforated cement sound-absorbing panels: made of MDF board, density 720kg/cu.m, thickness and area determine the actual weight. Aluminum fiber sound-absorbing panels: the lightest, with a surface density of only 1.4-3.2kg/㎡, suitable for weight-sensitive scenes.

Handmade rock wool sound-absorbing board: When the material is solid, a single piece (60×120×10cm) can reach 8-10kg, but it needs to be protected.
Sound insulation cotton board: Weight 1.3kg/㎡ (50mm thick), suitable for simple sound insulation needs.

Key factors affecting weight

Material: Aluminum fiber is the lightest, cement board is the heaviest, and gypsum and wood are in the middle.
Thickness: For example, the thickness of FC board is 6-15mm, and the increase in thickness directly leads to an increase in weight.
Specifications: Large-sized single pieces (such as 1200*600mm) are usually heavier, but the weight per unit area may be lower.
Tips: When purchasing, you need to balance weight and function. For example, theaters need lightweight fire protection (aluminum fiber), and machine rooms need high-density sound insulation (FC cement board).
