There are many kinds of fire-proof sound-absorbing panels on the market now, and the quality is different, which makes people dazzling. It is not easy to choose a good sound-absorbing panel. Some emphasize the effect of sound absorption, and some pay attention to the function of fire prevention. Modern architecture emphasizes the functionality and safety of decorative materials, and safety materials such as fire protection and environmental protection are welcomed by everyone. Many sound-absorbing panels are fire-resistant sound-absorbing panels, but fire-resistant sound-absorbing panels are also classified into Class A and Class B, so which ones The sound-absorbing panels are Class A fireproof and which ones are Class B fireproof. How to distinguish them? Let’s make a simple understanding.
The B-grade fire-proof sound-absorbing panels we refer to refer to the sound-absorbing panels that can meet the national fire protection standard of B-grade, which is divided into B1 and B2 grades. Class B2 is a combustible material that burns immediately in case of fire. Class B1 is a flame-retardant material. In layman’s terms, the sound-absorbing panel will burn in an open flame, but it will stop burning immediately when it leaves the fire source, and there will be no dripping in the air. Many sound-absorbing panels on the market are mostly B1-level flame-retardant materials. B1-level flame-retardant materials include: polyester fiber sound-absorbing panels, wood sound-absorbing panels, ecological wood sound-absorbing panels, fabric sound-absorbing panels, etc. The sound-absorbing panels listed above have a very The good commonality is that the sound-absorbing decoration is strong and the sound-absorbing performance is good. Their sound-absorbing performance is different. According to the high, medium and low frequency sound of the noise, it is very important to choose the correct sound-absorbing material.
The higher standard of the sound-absorbing panel is Class A, which is a non-combustible material, which can last for more than three hours under high temperature combustion. There are also many sound-absorbing panels on the market with a fire rating of A, such as ceramic aluminum sound-absorbing decorative fire-resistant panels, mineral wool sound-absorbing panels, clay panels, metal sound-absorbing panels, etc. The material used for these sound-absorbing panels determines its fire rating. Some A-class fireproof sound-absorbing panels not only have excellent noise reduction and sound absorption performance, but are also effective for medium and high frequency sound absorption. What’s more, it has good fire resistance, it is an inorganic material product, A-grade non-combustible, the product does not contain formaldehyde, heavy metals and other harmful substances, it is the safest and most reliable. For example, like mineral wool sound-absorbing panels, the combustion performance reaches A2 level non-combustible, and it is waterproof, moisture-proof, moth-proof, mildew-proof and antibacterial. It is strong and easy to process. Various specifications and sizes, suitable for office buildings, banks, airports, stations, theaters, museums, libraries, gymnasiums, multi-purpose halls, shopping malls, hospitals, schools, conference rooms, studios, recording studios, computer rooms, workshops, etc. Places where sound-absorbing decoration is required.
