CeilingsCeilings are described as being either:1. tightly attachedor2. suspended
These are basically the only options for installinga ceiling in a space;tightly attached means that the ceiling isattached to the underside of the structure directlyabove:this could be the underside of the floor above, or theunderside of the structural pieces above (such asa floor slab, beams, trusses, bar joists, or otherstructural elements
or:the ceiling is suspended from thestructure above by a variety of means,such as wires, cables, wood framing,steel framing, et cetera.
So, ceilings are able to be locatedfrom the highest available point in a space(like the underside of the floor structure above)down to the allowable code minimum lowestpoint in a space, which for human occupiablespaces is typically 7'-6" above the finishedfloor surface.
Suspended ceilings always have someamount of space that is open (sometimesvery little, sometimes very large) abovethe ceiling up to the structure above.
Plenum Space This space above the suspended ceiling is called a plenum space. this is typically used as a space in which tolocate HVAC ductwork, sprinkler pipes,recessed lighting fixtures, electricalconduit, and other systems components
a typical suspended ceiling system:suspension wires, a metal grid & modular panels
Interstitial Space In some large buildings the amount of mechanicalequipment is so great that an entire floor space isdedicated to this equipment. This kind of mechanical floor space is called aninterstitial space. Hospitals frequently have this type of space becausethey have a tremendous amount of equipment thatprovides fluids, gases, and complex heating and coolingneeds for a hospital.
Ceiling system manufacturers The major manufacturers of ceiling systems inthe United States are: US Gypsum Armstrong
Ceilings in commercial spaces Ceilings in public, commercial, spaces typically perform manycomplex functions:Spatial definitionAcoustical controlElectric lightingDaylight interaction: reflection/distributionContainment of systems components: hvac, electric wiring, sprinklerpipes, security cameras, speakersFire resistanceAbuse resistanceMoisture controlVisual Aesthetics
Noise Reduction Coefficient (NRC) Acoustical control Within a space the Noise Reduction Coefficient (NRC) ofmaterials expresses that materials’ ability to absorbsound. For a ceiling panel to be considered ‘acoustical’ it musthave a minimum NRC of .50. In an open office area a minimum NRC of .70 isrecommended.

Luxalon metal suspended ceilings are fully tested for reaction to fire, and are classified A2,s1,d0 according to EN 13501-1 and will therefore not contribute to possible fires. When ceilings however need to protect structural integrity of the building, Luxalon ceilings offer a range of practical and tested solutions with regards to
FIRE BEHAVIOUR Luxalon metal suspended ceilings are classified according to EN 13501-1 as non-combustible and will therefore not contribute to possible fires.
