Non woven fabric wrapped glass wool board in stock supply

The 6-centimeter thick glass wool board is wrapped with fireproof and transparent fabric after being cured with glue to form a sound-absorbing wall panel that is both beautiful and easy to install. The common sizes are 1.2m × 1.2m, 1.2m × 0.6m, 0.6m × 0.6m, with a thickness of 2.5cm or 5cm. There are also sound-absorbing ceiling panels formed by directly spraying transparent decorative materials on the surface of 110Kg/m3 glass wool. Whether it is glass wool sound-absorbing wall panels or sound-absorbing ceiling panels, high capacity glass wool needs to be used and strengthened to prevent deformation or excessive softness of the panels. This type of building material has both good decorative properties and retains the excellent sound absorption characteristics of centrifugal glass wool, with a noise reduction coefficient NRC generally reaching 0.85 or above.

In large spaces such as sports halls and workshops, centrifugal glass wool is often used as the main sound-absorbing material for sound absorption and noise reduction. Sound absorbers can be made into plate-like, columnar, conical, or other irregular shapes according to requirements. The interior of the sound absorber is filled with centrifugal glass wool, and the surface is wrapped with a sound transmitting surface layer. Due to the multiple surfaces of the sound absorbing body, the sound absorption efficiency is very high. In road sound barriers, in order to prevent noise reflection, sound-absorbing measures need to be taken on the side facing the vehicle. Centrifugal glass wool is often used as a filling material, and the barrier board is made of perforated metal plate as the surface layer.After the glass wool board material enters the site, it must have a factory certificate of conformity and an inspection report. After entering the site, it must undergo a retest and be qualified for installation and construction. After the completion of the keel construction, a fireproof glass wool insulation layer is laid in the keel interlayer. The glass wool external insulation wall is composed of three parts: the wall structure layer, the insulation layer, and the decorative layer, which have distinct functions. The main technical key to making a good external insulation wall is to connect the insulation layer with the structure layer.
