The fibers inside this type of warm glass wool felt 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 the glass wool, the sound waves 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.

The fibers inside the warm universal glass wool felt 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 the glass wool, the sound waves can enter the material through the pores, causing the air molecules in the gaps 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.

Suitable for insulation of various types of cold and hot pipes and hidden and exposed pipes.

Thermal conductivity

≤0.043 at 70℃

The use of fine fibers increases the number of fibers, improves the insulation effect, and compared to 80K rock wool, 16~24KAclear can achieve equal or better insulation performance. It can reduce the weight of insulation materials by 70~80%, achieving significant lightweighting.

The fiber refinement technology improves the sound absorption performance and can improve the sound insulation performance.

No materials containing formaldehyde are used during the production process, achieving a comfortable indoor air environment.

By changing the adhesive, the peculiar odor of glass wool and rock wool is also eliminated.

Formaldehyde-free glass wool makes the feel of glass wool softer by improving adhesives and refining fibers, which greatly reduces the tingling sensation unique to traditional rock wool and glass wool, and also improves the on-site working environment.

Glass wool has passed the GB8624-2006 combustion performance A2 test, with a combustion grade of A2 and produces no toxic gas or smoke.
