An acoustic ceiling offers the best opportunity for introducing noise mitigation, especially if it covers a large percentage of a room.2 A study revealed restaurants with acoustic panels in a suspended grid ceiling scored better on both speech privacy and speech intelligibility, and lower on noise annoyance, compared to restaurants with exposed ceilings and no acoustic control.3
Cleanliness
The customer’s perception of cleanliness is also of great importance to a restaurant’s atmosphere. Appearance is psychologically linked to food purity and freshness; thus, a clean-looking restaurant makes guests feel safer. The types of soiling common in the front of house are different than the back of house, and include dust, dirt from the street, spilled food and drink, smoke, and airborne pollution. Ceilings are also subject to soiling in areas near HVAC diffusers. Black or gray discoloration is created by particulates from ventilation streams which attach to ceilings due to the Coanda effect—the tendency of a fluid jet to stay attached to adjacent surfaces. Ceilings should be selected with regard to their ability to be vacuumed, swept, wiped, and washed. Painting can also refresh the appearance of dirty ceilings. However, if not done carefully, it can impact the appearance and noise reduction properties of perforated panels and absorbent materials such as mineral fiber.
Fire safety
The International Building Code (IBC) classifies restaurants under Group A (Assembly) occupancies, but the occupancy classification (and therefore, requirements) of a particular restaurant may depend on its size, the occupancy classification of the overall building in which it is housed, and the code for the region in which it is located. Group A occupancies generally require ceiling finish materials with a flame spread of no more than 150, or no more than 75 if the location is not sprinklered, tested according to ASTM E84.
Again, designers should consult all applicable codes to determine what ceiling materials are acceptable in a particular project.
Lighting levels
Depending on their location, lighting fixtures may or may not involve the ceiling. An intimate setting might only be illuminated by indirect lighting, but a large, cafeteria-style establishment will likely have troffers, downlights, or a luminous ceiling. Light reflectance of all surfaces, including the ceiling, will affect both illumination efficacy and the room’s ambience. A highly reflective ceiling may help meet the adequate lighting requirement.
Front-of-house options
For new construction projects, almost anything—within the safety constraints of building codes—is possible, such as a restaurant ceiling festooned with empty Chianti bottles. However, the following examples constitute some of the more readily available commercial ceiling options for front-of-house areas.
Hard-lid ceilings
Hard-lid ceilings made from gypsum board, plaster, or beadboard are appropriate in many places, and depending on their painted finishes, they are durable and washable. However, they require access hatches to reach overhead services and offer little noise attenuation.
