Noise Reduction Heat Insulation Glass Wool Mat Flame Retardant 600mm

product features

Glass wool board is a kind of high-quality building material, which is high in quality and low in price, and at the same time beautiful, fireproof, moisture-proof, dust-proof, and aging-resistant. Different from other fire-proof and sound-proof materials, glass wool board can be cut at will, and its physical properties are stable.

Centrifugal glass wool is the most important kind of glass wool, and it is also the constituent material of most glass wool boards. When sound waves enter the centrifugal glass wool, the sound waves can enter the material along the pores of the glass wool, causing the air molecules in the gaps to Due to the viscous resistance of air and the friction between air molecules and pore walls, sound energy can be converted into heat energy and lost. The thicker the glass wool board, the better the suction effect.

Applications

Glass wool board has excellent properties such as fire prevention, heat preservation, and easy cutting, and is one of the most commonly used materials for building sound absorption. However, glass wool itself also has certain shortcomings. The surface of glass wool is not decorative, and there will be some tiny fibers scattered, so in actual use in life, glass wool is mostly used as the internal material of sound-absorbing components, or in glass wool boards. The surface is perforated with some acoustically transparent material. The size of common glass wool boards is mostly 1.2m×1.2m, 1.2m×0.6m, 0.6m×0.6m, and the thickness is 2.5cm or 5cm.

In addition to being used for sound insulation and heat insulation of ordinary external walls, glass wool panels are also used in the construction of large venues. In such large spaces that require higher sound absorption, glass wool is often made into large sound-absorbing bodies of other shapes. , In addition, glass wool boards are also used for sound insulation shielding of roads.
