Suspended ceilings
In many restaurants, the overhead structure is left exposed to add visual height to the space and an industrial aesthetic. While this can be economical, savings are reduced by the extra efforts required to make structural members, ducts, and other equipment visually presentable. The added volume can also require additional lighting and air-conditioning capacity.
Most commercial buildings use suspended ceilings to conceal, yet allow access to, above-ceiling cavities which host services such as plumbing, ductwork, electrical, and fire-suppression systems. The most versatile suspension system is the T-bar suspension system conforming to ASTM C635/C635M, Standard Specification for Manufacture, Performance, and Testing of Metal Suspension Systems for Acoustical Tile and Lay-in Panel Ceilings, with either a 610 x 610 mm (24 x 24 in.) or 610 x 1220 mm (24 x 48 in.) module.
While the grid imposes a visual order, the overall character of the ceiling depends on the style of tiles or panels in the grid. Although the flat, white expanse of drop-in mineral fiber panels is common, other options have greater decorative properties, such as three-dimensional panels that create textured, patterned ceilings in a range of styles and colors. If an existing ceiling grid is discolored or damaged, T-bars can be repainted or, to reduce time and labor required, covered with adhesive-backed decorative strips or snap-on grid-cover strips in colors which match or complement ceiling panels.
The standard for mineral fiber and other similar panels, ASTM E1264, Standard Classification for Acoustical Ceiling Products, details certain performance properties. No such similar standard has been written for metal, wood, or thermoformed ceiling panels.
Metal ceilings
Metal ceiling panel systems are made in a great variety of styles, shapes, and finishes. Perforations in panels can improve sound attenuation, and batt insulation or non-woven acoustic fabric backing can improve performance.
Wood ceilings
Wood ceilings can have a biophilic appeal. To achieve acoustic performance, perforated, slat, or open-cell products can be used. Light reflectance depends on the color of the wood. Wood ceilings may be heavy, and the load must be calculated to ensure it can be supported above.
Thermoformed ceiling panels
Thermoformed panels are relatively lightweight, made from thin sheets of rigid plastic. They are easy to install, and available in a wide palette of colors and three-dimensional decorative patterns. When made from transparent or translucent materials, they can be installed as luminous ceilings beneath economical, color-controlled light-emitting diode (LED) strips. The color of the light can be programmed with a digital multiplex (DMX) controller. This allows the ceiling to change color and lighting intensity throughout the day to create different lighting schemes for the breakfast, lunch, dinner, and late-night crowds, an advancement of the concept known as dayparting in the hospitality industry (Figure 1).
