Office Ceilings

Wavebar™ barriers

Wavebar™ barriers are dense, flexible curtains that deflect noise.

• More flexible, practical and economical than full height partitions.
• Improves confidentiality by virtually eliminating noise form adjacent rooms. Provides privacy and peace of mind in directors offices, board rooms, consultation rooms, computer rooms, hallways, nurseries, etc.
• Easy to install, ideal for refurbishments. Simply suspend from slab to ceiling tiles. No additional framework is necessary.
• Proven project history. WAVEBAR™ has been utilised in office fit-outs and refurbishments for more than 3 deacades as a safe and reliable way to reduce room-to-room noise transmitted via common ceiling.

Improve Workplace Effectiveness

Sound absorbtion is a primary design criterion for ceiling tiles. A ceiling tiles ability to absorb sound is measured in three ways.

NRC - Noise Reduction Coefficient

Measures the average percentage of noise a material absorbs at four frequencies. This key measure of absorbtion of generla office noise is expressed as asinlge value percentage, with a genreally acceptable maximum value of 0.70 and a preferred value of 0.75 to 1.00 in open pan office.

AC - Articulation Class

Rates a ceilings suitablity for achieving normal privacy in open office spaces by absorbing noise reflected at an angleof the ceiling inot adjacnet cubicles. The angles simulate the movement of reflected sound waves passing over the office paretitions in the frequencies criticle to speech intelligibility and conversational privacy. The generally accepted AC rating for normal privacy in open plan is minimum 170, with 190 or 210 preffered. AC is the primary measure of acoustics in the open plan.

CAC - Ceiling Attenuation Class

Rates a structures efficiency as a barrier of airborne sound at 16 speech frequencies. It is an especially significant measure in providing acoustic proivacy between adjacnet work areas, where sound can penetrate plenum spaces and carry to other spaces. CAC is stated as aminimum value; CAC minimum 25 is acceptable in open plan offices, while a rating minimum 35 or 40 is preffered for closed offices.
