Acoustics is literally at the centre of SAS. The acronym stands for Special Acoustic Services. We are proud of our pioneering and long-standing position as market leaders of acoustically performing metal ceilings.
SAS achieve superior aesthetics, performance and delivery through our comprehensive acoustical knowledge, design expertise and technical leadership. We use advanced acoustical modelling techniques and in-house test facilities to develop new products and improve existing ones. In order to provide our clients expertise and meet their building requirements, SAS offers support from an in-house acoustical specialist.
Given that the ceiling is such a significant surface, it is essential that a sound absorbing product is employed in this area to control reverberance and occupational noise. A suspended ceiling is often a suitable solution, though if the thermal mass of the soffit needs to be exposed, rafts or baffles can be employed.
SAS products absorb sound using an open-cell porous material faced with a perforated metal sheet. Most ceiling tiles rely entirely on the porous material behind the perforated metal to absorb the sound. Micro-perforated tiles are the exception and can offer sound absorption without a distinct porous backing. In both cases, sound is absorbed because the air particles have to vibrate within a medium that limits this movement. Porous absorbers are most effective when they coincide with air that is vibrating a lot. However, the vibration of air particles is not the same at every frequency or in every location within a room. As such, the effectiveness of a sound absorber is dependent on where it is placed.
SAS’ clients benefit from our design expertise, manufacturing capabilities and product quality as well as our specialist acoustic guidance including advice on acceptable levels of acoustical privacy, reverberance and the acoustical characteristics of various type of spaces.
The confidence and assurance that SAS delivers is exemplified through the awards and accreditations achieved by the projects we have been involved in.
