Aesthetics, acoustics and durability all play a role
Contractors who install acoustical ceiling systems in commercial applications are discovering what we in the ceilings industry have been observing for quite some time: the growing use and popularity of metal ceiling systems.
One of the main reasons for their popularity is that architects and designers like the sleek, upscale, high-tech look metal brings to a space.
This sophisticated look makes them ideal for use in high-visibility areas, such as lobbies, entryways, conference rooms, corridors, theaters and transportation terminals, along with a wide variety of corporate, retail and hospitality environments.
Another reason is the service life of metal ceilings. Usually made from steel or aluminum, metal ceiling panels are often chosen because of their durability, especially where access to the plenum is frequent. Their toughness is also important where the ceiling is exposed to occupant interaction, frequent cleaning or other potentially damaging situations.
Many metal ceilings feature a factory-applied powder-coated finish for added durability. Humidity resistance and low maintenance are other important considerations in the selection of metal.
Aesthetics plus acoustics
Metal ceilings can provide acoustical control as well as eye-catching aesthetics. To achieve the acoustic benefits, the panels must be perforated. Perforated panels are usually supplied with a black, soundabsorbent acoustical fleece or optional fiberglass infill behind the perforations. Perforations vary in size and pattern depending on aesthetic appeal. Today it’s possible to have perforated panels in which the holes are so small, they are essentially invisible. For example, perforations in Lancaster, Pa.- based Armstrong Ceilings’ Extra Microperforated MetalWorks ceilings measure only 7/10 of a millimeter in diameter. Yet, they allow the panels to achieve a Noise Reduction Coefficient (NRC) of 0.65, meaning the panels absorb 65 percent of the sound that strikes them.
Variety of finishes, shapes
Metal ceilings are offered in a variety of finishes that coordinate with other interior metal finishes. The most popular finishes are white, silver grey, and gun metal grey in color, with custom colors available as well. There are also metal ceiling panels that provide the rich, warm look of wood at a more affordable cost. One example is MetalWorks Effects ceilings from Armstrong. This ceiling is made possible by a technology that actually embeds a realistic image of maple, cherry or walnut onto the surface of a metal ceiling panel. The powder-coated finish
(post-coated) produces a consistent color tone and grain, greatly reducing the variations that occur in real wood panels. And, the panels can be perforated for acoustic control.
Armstrong also offers MetalWorks Torsion Spring ceilings with real wood veneers. These ceilings are available in three standard veneer finishes: maple, light cherry, and dark cherry. Custom finishes are also available. In terms of shapes, the most common choice is a 2- by 2-foot panel. Metal ceilings are also available in linear versions, as well as both radial and curved systems in an assortment of sizes. Other choices include a variety of “free-floating” clouds and canopies, as well as undulating 3-D metal ceilings that are available in “hills” and “valleys” to create a serpentine or wave effect.
Ease of installation
Metal ceilings install easily in standard suspension systems and integrate well with standard light fixtures and high hats. Many are designed for installation in 15/16-inch exposed tee suspension systems, which makes them ideal for renovation applications as well as new construction. Because there is no need to replace an existing suspension system, renovation projects can be completed quickly. Other metal ceilings can be installed in 9/16-inch suspension systems. In the case of “free-floating” clouds and canopies, installation is made even easier through the availability of kits containing all the components required for the job. All components are pre-engineered for fit and finish to help ensure consistent visual quality. They also allow faster and easier installation since the system requires no field modification, only assembly.
As you can see, today’s metal ceiling systems are easy to install and offered in more sizes, shapes, colors, finishes, edge details and patterns than ever before. Is it any wonder that they continue to grow in popularity?
