Centrifugal glass wool felt is a roll material made to meet the needs of large-scale installation. In addition to maintaining insulation and heat insulation characteristics, it also has excellent shock absorption and sound absorption properties, especially good absorption effects on medium and low frequencies and various vibration noises, which is conducive to reducing noise pollution and improving the working environment.
This material can be cut as needed during construction and is mainly used for shock absorption, sound absorption, and noise reduction in indoor buildings, noise reduction systems, transportation vehicles, refrigeration equipment, and household appliances. The effect is very ideal.
Glass wool felt with aluminum foil veneer and strong heat radiation resistance is the lining material for high-temperature workshops, control rooms, machine room walls, partitions, and flat roofs.
Glass wool belongs to a category of glass fibers and is an artificial inorganic fiber. Using natural ores such as quartz sand, limestone, and dolomite as the main raw materials, combined with some chemical raw materials such as soda ash and borax to melt into glass. In the melted state, with the help of external force, the blowing system throws into flocculent fine fibers, and the fibers intersect in a three-dimensional manner, intertwining with each other, presenting many small gaps. This gap can be regarded as a gap. Therefore, glass wool can be regarded as a porous material with good insulation and sound absorption properties.

Introduction to the price and performance of centrifugal glass wool roll felt

Centrifugal glass wool is a filamentous material made by fiberizing and spraying thermosetting resin onto glass in a molten state using centrifugal blowing technology, and then undergoing deep processing and heat curing treatment to produce a series of products with multiple uses. It has many advantages such as flame retardancy, non toxicity, corrosion resistance, low bulk density, low thermal conductivity, strong chemical stability, low moisture absorption rate, and good hydrophobicity. It is currently the most high-performance insulation, heat insulation, and sound absorption material with a wide range of applications. The boards, felts, and pipes made of this material have been widely used for insulation, sound absorption, and noise reduction in fields such as construction, chemical engineering, electronics, power, metallurgy, energy, and transportation, with significant effects.

Due to its soft texture and fine fibers, centrifugal glass wool is not irritating to the skin during construction and is therefore highly favored by construction units as a thermal insulation product.

Product Usage

Glass wool felt and sound-absorbing cotton felt are ideal materials for sound absorption and thermal insulation, widely used for building walls and ship engine room insulation; Computer room and refrigeration room with constant temperature; Noise reduction in various generator rooms and pump rooms; Audio cabinet, audio adjustment, etc.

Sound absorption coefficient:

When using glass wool felt and sound-absorbing cotton felt as sound-absorbing materials, leave an air layer behind them or stick decorative materials on the surface. Within the range of 100-150mm thickness of the air layer, the thicker the air layer, the higher the sound absorption rate in the mid to low frequency range. If the air is thickened to 300mm, the effective sound absorption rate range expands to 100Hz.

Product use: Function: Wall sound absorption, wall sound insulation, wall thermal insulation, wall thermal insulation.

Centrifugal glass wool has fluffy and interlaced fibers inside, with a large number of tiny pores, making it a typical porous sound-absorbing material with good sound absorption properties. Centrifugal glass wool can be used to make wall panels, ceilings, spatial absorbers, etc., which can absorb a large amount of sound energy in the room, reduce reverberation time, and minimize indoor noise.
