Package inspection - Red glass wool board priceIt can achieve greater sound absorption effect. For example, stacking a layer of 2.5cm thick 24kg/m3 cotton board with a layer of 2.5cm thick 32kg/m3 cotton board has better sound absorption effect than a layer of 5cm thick 32kg/m3 cotton board. Make a glass wool board with a capacity of 24kg/m3 into a 1m long triangular wedge with a gradually increasing surface density, and the average sound absorption coefficient can approach 1.

In the use of centrifugal glass wool in construction, the surface often needs to be decorated with a certain degree of sound transmission, such as plastic film, metal mesh, window screen, fireproof cloth, glass fiber cloth, etc., which can basically maintain the original sound absorption characteristics. Centrifugal glass wool has excellent characteristics such as fire resistance, insulation, and easy cutting, and is one of the most commonly used materials for building sound absorption. However, due to the lack of decorative properties on the surface of centrifugal glass wool and the possibility of fiber scattering, various sound-absorbing components must be made for concealed use. The most commonly used and cost-effective construction is the perforated paper faced gypsum board ceiling or the perforated board wall filled with centrifugal glass wool. When the perforation rate is greater than 20%, it can basically exert the sound absorption performance of centrifugal glass wool.The construction part that blocks external noise indoors, such asktvKaraokPlaces such as cinemas and opera houses that generate a large number of students are used to block the transmission of sound sources to the outside of buildings; Suitable for blocking external noise from entering indoor engineering parts, such as hotels, guesthouses, conference rooms, etc; Suitable for sound-absorbing home decoration. Product Features: It has a wide absorption spectrum, high absorption coefficient, and good absorption effect for low, medium, and high frequency noise. And it also has the characteristics of flame retardancy, fire resistance, aesthetics, elasticity, no dust pollution, strong decoration, and simple construction.To prevent the glass wool fibers from spilling out, it is necessary to attach a layer of non-woven fabric, mulberry paper or other transparent fabrics behind the perforated board, or wrap the glass wool with glass cloth, plastic film or other materials. Similar panels to perforated paper faced gypsum board include perforated metal panels (such as aluminum panels), perforated wooden panels, perforated fiber cement panels, perforated mineral wool panels, etc.
