The high-density centrifugal glass wool sandwich panel is a premium porous sound absorption and thermal insulation material widely used for building noise reduction, fire protection, and energy-saving insulation projects. Manufactured from high-purity glass fibers via professional centrifugal spinning technology, the board features a fluffy, randomly interlaced fiber structure with countless interconnected micro pores, delivering superior sound absorption and noise reduction performance compared with ordinary insulation materials.
As a professional soundproofing and thermal insulation solution, this glass fiber sound insulation board effectively eliminates indoor and mechanical equipment noise. When sound waves penetrate the porous surface, internal air molecules generate viscous friction and resistance, converting acoustic energy into heat energy to achieve stable, long-lasting noise reduction. It is the ideal sound absorption material for auditoriums, gymnasiums, recording studios, conference rooms, and industrial mechanical rooms.
A1 Fireproof Performance & Thermal Insulation Advantage
Fire safety is the core advantage of our glass wool insulation panel. The product passes the strict GB 8624-2012 A1 non-combustible fire rating, the highest fire resistance grade for building materials. It can withstand high temperatures up to 500°C without melting, burning, or releasing toxic and harmful fumes, ensuring full fire safety for commercial and industrial buildings.
In addition to excellent soundproofing and fireproof properties, the low thermal conductivity of the centrifugal glass wool board provides outstanding thermal insulation and heat preservation effects. It perfectly combines noise reduction, fire prevention, and energy-saving insulation in one material, effectively reducing building energy consumption and meeting modern green building engineering standards.
Standard Specifications & Customizable Parameters
We provide flexible and customizable glass wool insulation specifications to match diverse engineering and construction needs, supporting OEM and personalized size customization. Standard and mainstream parameters are as follows:
- Standard Size: 1200mm × 600mm
- Optional Thickness: 50mm, 100mm
- Density Range: 32kg/m³ – 80kg/m³ (adjustable for targeted acoustic and insulation performance)
This acoustic insulation board features excellent flexibility and elastic rebound. After compression, it can quickly restore its original porous structure, avoiding deformation and performance attenuation during long-term service. The stable physical structure ensures consistent sound absorption and thermal insulation effects throughout the product service life.
Easy Installation & Cost-Effective Construction
The glass wool sandwich panel is designed for fast and convenient on-site installation. It can be cut and processed with conventional construction tools without professional construction skills or complex procedures. The simple installation process greatly shortens the construction cycle and reduces labor costs, making it a highly cost-effective HVAC noise reduction and building acoustic solution.
Stable Quality & Strict Industry Compliance
Our customizable glass wool insulation boasts excellent chemical stability and strong corrosion resistance, resisting daily environmental erosion and extending the service life of building insulation and acoustic systems. All products are strictly produced and tested in accordance with GB/T 13350-2017 and GB/T 17795-2019 national standards. Every production batch undergoes rigorous quality inspection to ensure stable, reliable, and standardized product performance.
Wide Application Scenarios
Due to its integrated advantages of sound absorption, fire resistance, thermal insulation, and easy installation, the centrifugal glass acoustic insulation board is widely applied in multiple commercial, civil, and industrial scenarios:
- Indoor acoustic treatment: Gymnasiums, auditoriums, lecture halls, conference rooms, recording studios, and broadcast studios
- Industrial noise control: Mechanical room soundproofing, equipment noise reduction
- HVAC system engineering: HVAC duct noise reduction, pipeline thermal insulation and wrapping
- Building wall insulation and soundproofing for residential and commercial buildings
