1. Main features
Sound insulation performance: It blocks the propagation of sound waves through a high-density fiber structure, and is particularly effective against medium and high-frequency noises (such as human voices and mechanical noises).
Sound absorption performance: The porous structure causes sound waves to be reflected and attenuated between fibers, converting them into heat energy and reducing echoes and reverberation.
Lightweight and durable: It is lighter than traditional sound insulation materials (such as concrete), easy to install, and resistant to corrosion, moisture and mold.
Fire resistance: Most products meet the A-level non-combustible standard and are suitable for places with high fire protection requirements.
Environmental friendliness: Some products use recyclable glass fibers, but it should be noted that fiber dust may be generated during construction (protection is required).
2. Common application scenarios
In the field of architecture: walls, ceilings, floor partitions (such as recording studios, cinemas, office partitions).
Industrial equipment: Wrapping noise sources such as fans, pipelines, generators, etc.
Interior sound insulation layers for vehicles: automobiles, ships and aircraft.
Home scenarios: home theater, bedroom sound insulation renovation.
3. Type and Form
Panel: Rigid plate type, which can be directly installed on the wall or ceiling.
Roll material: Flexible roll shape, suitable for wrapping pipes or curved surface structures.
Composite type: Combined with other materials (such as gypsum board, aluminum plate) to enhance strength or aesthetics.
4. Installation Precautions
Sealing treatment: The joints should be sealed with sealant or special tape to prevent the sound bridge effect.
Multi-layer structure: It is often used in combination with sound insulation felt and shock-absorbing pads to enhance the low-frequency sound insulation effect (such as the "mass - spring - mass" structure).
Safety precautions: Wear a mask and gloves when cutting to prevent the fibers from irritating the skin and respiratory tract.
5. Comparison of advantages and disadvantages
Advantages and disadvantages
Lightweight and easy to install, with weak low-frequency sound insulation effect (needs to be combined with other materials)
Inferior fireproof and moisture-proof products may release fiber dust
It has a high cost performance but low hardness and requires an additional protective layer
Environmental protection certification: The products of this enterprise comply with ISO 14001 or green building materials standards.
