Glass wool felt is a kind of thermal insulation material commonly used in construction engineering. It has the thermal insulation performance of glass wool products and good sound absorption and noise reduction performance. It is not only a good insulation material inside and outside the building, but also the best choice to eliminate noise in the space. Let's take a look at where the excellent sound absorption properties of glass wool felt come from.
The density of glass wool felt sold in the building materials market generally does not exceed 60kg/m3, the sound insulation effect is not good and the hand feel is very soft, and it is easy to completely lose its sound insulation function due to sagging; glass wool felt is the oldest and most widely used sound absorbing material. It is widely used in sound insulation, heat preservation and fire prevention of light wall.
The lightweight wall behind the glass wool felt is 8 to 15 decibels better than the gypsum board without the centrifugal glass wool felt. The glass wool felt board is different from the inferior centrifugal glass wool felt sold on the market. The centrifugal glass wool felt board is a new product specially developed for light wall sound insulation, and has been fully acoustically optimized. : Density - The density of glass wool felt board is set to 100-200kg/m3, which is the best density for wall sound insulation, which not only guarantees the best sound insulation, but also guarantees the wall and the material itself. Strength of.
Glass wool felt board is convenient for construction. According to the standard spacing of the keel, the width is determined to be 800mm, 600mm, 400mm, etc., so that it is not necessary to cut the price of the A-grade fireproof rock wool board during construction, thus reducing the centrifugal glass wool felt The stimuli of the construction workers. The centrifugal glass wool felt sold in the building materials market is limited to equipment and other reasons, and generally needs to be cut at the construction site. After optimized design, the centrifugal glass wool felt board can improve the sound insulation effect of the light wall by more than 10 decibels.
