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.
