Curtain wall noise reduction uses aluminum honeycomb panel and punched aluminum veneer-which performance is better

Do business in the building decoration industry, all kinds of high-priced and low-priced goods need to know, the cheapest or plastic decoration Products, glass curtain wall is more commonly used, but when it comes to high prices, have to mention punching aluminum veneer and aluminum honeycomb panel, we or more or less have heard of it? Artistic punching aluminum veneer, excellent performance of aluminum honeycomb panel, they all have a certain noise reduction performance. So, of the two, whose noise reduction performance is more excellent??

To compare the noise reduction and sound insulation performance of the two, it is necessary to discuss the structure of the two.

Punched aluminum veneer is also called perforated aluminum veneer. It is made of single-layer aluminum plate. The punching hole with its distinctive characteristics is made by CNC punching machine. When it comes to noise reduction and sound insulation, it is because due to the existence of holes, the propagation route of sound waves in the air is disturbed, so that part of the sound waves are emitted, thereby achieving the effect of noise reduction.

Different from punched aluminum veneer, the structure of aluminum honeycomb panel is relatively complex, mainly composed of panel and bottom plate, with high-quality aluminum honeycomb core attached in the middle. Aluminum honeycomb core generally adopts the form of regular hexagonal honeycomb structure, forming a number of closed small space, thus preventing the air flow, sound waves are hindered, 100-3200HZ sound source noise reduction sound insulation up to 20-30 decibels, the effect is very prominent.

After the actual test, punching aluminum veneer and aluminum honeycomb panel have a certain noise reduction and sound insulation performance, but the sound insulation and noise reduction performance of aluminum honeycomb panel is better. However, both of them can be improved in noise reduction and sound insulation performance. For example, perforated aluminum veneer can be attached with some sound-absorbing rock wool inside, and aluminum honeycomb panel can also be punched.
