Wall sound insulation cotton
The fibers inside hbc glass wool are fluffy and interlaced, and there are a lot of tiny pores. It is a typical porous sound-absorbing material with good sound-absorbing properties. When sound waves are incident on glass wool, they can enter the material through the pores, causing the air molecules in the pores to vibrate. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into heat energy and lost.

Product Introduction
Application
The fibers inside hbc glass wool are fluffy and interlaced, and there are a lot of tiny pores. It is a typical porous sound-absorbing material with good sound-absorbing properties. When sound waves are incident on glass wool, they can enter the material through the pores, causing the air molecules in the pores to vibrate. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into heat energy and lost.
HBC glass wool is widely used in building sound insulation structures, equipment noise reduction devices, pipe inner wall sound absorption and noise reduction, etc.
Product Performance
Sound absorption performance
Strong flame retardancy
Easy construction
Safety and environmental protection
HBC glass wool has good sound absorption performance for mid- and high-frequency sounds. When sound waves pass through the fiber pores, they resonate with the extremely light microfibers under the effects of countless reflections and friction losses, and continuously reduce the energy of the sound waves, so that the amount of reflection and passing of the sound waves is quickly reduced to a minimum, and the sound absorption efficiency is higher than other sound-absorbing materials.
hbc glass wool is a Class A non-combustible material. It can maintain good performance even at a high temperature of 350°C. It does not produce toxic or harmful gases, smoke, slag or flame spread when encountering fire.
Easy to install and reduce labor costs.
It has extremely high construction convenience and excellent cost performance, better insulation and decorative effects and lower overall cost.
