Application

Glass Wool are widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.

Q: How much is the unit weight of thermal insulation glass?wool?boards at least? How much is the unit weight of sound absorption glass panels?: They are from twenty to less than eighty.

Q: Is the glass wool used in curtain wall the thermal insulation wool?: The glass wool used for curtain wall is thermal insulation wool.However, due to the need of fireproofing, the thermal insulation material for curtain wall normally is rock wool.

Q: Can Kunnai glass wool board and sound absorption blankets be used to maintain sound insulation in hotel floor? Can it decrease half of the noise? How to install?: No estimate half, but still able to play a sound effect

Q: What are the differences between glass wool felts and rock wool board in terms of appearance, and how to distinguish them?: The most significant difference is color. Glass wool is white, while rock wool is yellow.

Q: Is the microporous aluminum silicate coated with aluminum wool?: Aluminum silicate is white fiber

Q: To reach better sound absorption effect, which should be filled in the keel, glass wool felt / board or polyester fiber cotton felt / board ?: Glass wool board Glass wool board is mainly used for sound insulation. Glass wool felt is mainly used for thermal insulation, and polyester fiber cotton felt is mainly for thermal insulation and sound absorption.

Q: What are the features of glass wool decorative acoustic?panel?absorber suspended ceiling?: Five features of glass wool decorative acoustic?panel?absorber: 1, Glass wool decorative acoustic?panel?absorber suspended ceiling has excellent sound absorption performance. Installatiion cavity behind the buildings ceiling is usually greater than 200mm. Low frequency sound absorption coefficient will increase greatly as the cavity increases, so the glass fiber ceiling can reach the strong effect of full-range sound absorption. 2, Glass wool decorative acoustic?panel?absorber suspended ceiling surface has no color, so it has a good decorative effect. 3, Glass wool decorative acoustic?panel?absorber suspended ceiling has good fireproof?performance. As the main raw material of the board is incombustible?material, it can reach class A fire?rating. 4, The board of glass wool decorative acoustic?panel?absorber suspended ceiling is light and thin. The board is thin and light and the density is about 2.O ~ 3.Okg / mz, so it is easy to transport and store. 5, Structure of glass wool decorative acoustic?panel?absorber suspended ceiling is simple, so it is easy to install. Glass fiber decorative acoustic ceiling does not have decorative protective surface layer as other glass fiber boards and it will not have fiber scattered which will pollute the environment. So the construction site is clean. It is easy to install with metal keel, both exposed keel or concealed keel. It is also easy to repair and exchange. Besides, it is relatively safe because it add little load to architectural?structure.

Q: Who can tell me about the unit weight of glass wool board?: Glass wool has a good sound absorption performance in the high-frequency sound. The main factors affecting the centrifugal glass wool' sound absorption performance are thickness, density and air flow resistance, etc. Density is the weight per cubic meter of materials. 1. with the increase of thickness, the low frequency sound absorption coefficient significantly increases, but there is little change in the high frequency (high frequency absorption is always larger). 2. thickness is the same, the unit weight increases, the low frequency sound absorption coefficient also increases; but when the unit weight increases to a certain extent, the material becomes dense, the flow resistance is greater than the optimum flow resistance, sound absorption coefficient decreases.

Q: What is the difference between glass wool and rock wool?: In the high-speed operation of the centrifuge driven, the high-speed operation of the centrifuge glass will be thrown into a glass flow, the role of high-temperature high-speed flame, the glass stream is further drawn into fiber,
