Info

Lighting Fixture Quantity: The amount of the lighting fixtures required in the space to which the suspended ceiling is applied. Lighting Fixture Size: The sizes of the lighting fixtures to be placed within the plenum. Lighting Fixture Weight: The weight of the lighting fixture to be used within the suspended ceiling system. Load Test Data: The load carrying capacity of the main beams and the cross tees of the suspended ceiling. Main Runner and Cross Tee Color: The color of the main runners and the cross tees. Main Runner and Cross Tee End Detail: The detail of the uppermost part of the profiles which is used to connect the profiles to the hangers (e.g. peaked or straight). Main Runner and Cross Tee Face Dimension: The width of the lowest part of the main runner and the cross tee. Main Runner and Cross Tee Interface: The connection detail of the main runners and the cross tees (e.g. override, or flushfit). Main Runner and Cross Tee Profile Length: The profile length of the main runners and the cross tees. Main Runner and Cross Tee Structural Classification: The classification of the system according to the load carrying capability of grid components in kilograms per meter. There are three types in general: heavy duty, intermediate duty, and light duty. Main Runner and Cross Tee Surface Finish: The type of surface finish applied to the main runners and cross tees. Main Runner and Cross Tee Web Height: The height of the main runner and the cross tee measured from the face to the top of the top bulb. Main Runner and Cross Tee Weight: The weight of the main runner and the cross tee. Maximum Air Diffuser Weight: The maximum allowed air diffuser weight in the suspended ceiling structure. Maximum Lighting Fixture Weight: The maximum allowed lighting fixture weight in the suspended ceiling structure. Panel Acoustics CAC: <strong>Ceiling</strong> Attenuation Class (CAC) rates a ceiling's efficiency as a barrier to airborne sound transmission between adjacent closed spaces. 209
Panel Acoustics NRC: Noise Reduction Coefficient (NRC) of the suspended ceiling panel rates of ability of a ceiling panel to absorb sound. This value may typically range from 0.4 to 1.00. Panel Antimicrobial Treatment: A treatment applied to inhibit or retard growth of mold or mildew on products' painted surfaces. Panel Color: The color of the suspended ceiling panel. Panel Edge and Joint Detail: The type of joint applied at the panel edges (e.g. reveal, flush reveal, square edge, etc.) Panel Fire Resistance: The suspended ceiling’s property of acting as a barrier to fire. Acoustical ceiling systems form a membrane to contain fire within a room. Fire-rated assemblies are given ratings of one, two, three, or four hours. Panel Humidity Resistance: The resistance of the suspended ceiling panel to the relative humidity. Standard acoustical panels are designed for installation within the normal occupancy condition range of maximum 70% relative humidity. When the in-service use relative humidity is expected to exceed this range, the use of acoustical units specifically designed for these applications should be considered. Panel Material: The material of the suspended ceiling panel. Panel Sag Resistance: The resistance of the suspended ceiling panel to sag. Panel Surface Pattern: <strong>Suspended</strong> ceiling panels may be one of or a combination of two or more of the following patterns: perforated, fissured, textured, smooth, printed, embossed, surface scored, and random swirl. Panel Surface Reflectance: The suspended ceiling’s property of reflecting light. The measure of light reflectance is that fraction of the specified incident light, which is reflected by the surface. Panel Thermal Insulation Value: (R factor) A number measuring a material's resistance to heat flow. R stands for resistance, the inverse of conductivity. Panel Thickness: The thickness of the suspended ceiling panel. Panel Weight: The weight of a single panel. Panel Width and Length: The width and length of the suspended ceiling panels. Plenum Depth: The space above the suspended ceiling in which beams, HVAC and lighting equipment are concealed. 210
