Controlling noise with metal ceiling systems
Specifiers who choose acoustical ceiling systems in commercial applications are discovering what the ceilings industry has observed for quite some time: the growing use and popularity of metal ceiling systems is a direct result of their eye-catching visuals, noise control, and long service life.To get more news about perforated metal ceiling, you can visit boegger.net official website.
One of the main reasons for their popularity is the sleek, upscale, high-tech look metal brings to a space. This sophisticated feature makes them ideal for use in high visibility areas, such as lobbies, conference rooms, corridors, theaters, and transportation terminals, as well as in several corporate, retail, and hospitality environments. Long popular in European commercial design, today’s metal ceiling systems are offered in a wider variety of sizes, forms, and shapes than ever before.
Durability is another reason for their growth. Metal ceiling panels are often chosen over other options because of their service life, especially in areas where access to the plenum is frequent or where the ceiling is exposed to occupant interaction, frequent cleaning, or other potentially damaging situations.
Most metal ceiling systems are manufactured from electrogalvanized steel or aluminum. Many of them also feature a factory-applied powder-coated finish for added durability. Humidity resistance and low maintenance are other important considerations in the selection of metal.
Specifiers do not always associate metal with good acoustics. Yet, metal ceilings can provide very effective acoustical control in addition to their eye-catching aesthetics, making them a versatile and functional design element. To obtain the acoustic benefits, however, the panels must be perforated and backed with a sound-absorbent liner behind the perforations, usually in the form of a thin black acoustical fleece, mineral fiber panels, and/or an encapsulated fiberglass infill.
Thickness, density, and mounting method affect the sound absorption of the backloaded acoustic material. In typical backloading applications, the material is laid on top of the perforated metal panels with an air gap between the material and the deck.
The number, size, and shape of the perforations also impact the acoustical performance of the ceiling panel. Depending on the perforations, sound can pass through the ceiling panels and be absorbed by the material behind them.
