Sound and light
Thermoformed panels provide noise reduction in a different way than mineral fibre panels. The lightweight thermoformed ceiling uses the viscous mass of air above the suspended ceiling to dampen vibration. For situations where acoustic control is most needed, the panels can be micro-perforated and installed with a backing to absorb 85 per cent of the sound impinging on the surface (NRC 0.85).
In the past, general lighting fixtures had to be located around the pool perimeter where they could be easily accessed for frequent replacement. Light was often directed upward to reflect off the ceiling to create uniform, glare-free lighting. For energy efficiency, ceiling surfaces should have a light reflectance value (LRV) over 90 per cent.
Some designers are rethinking this approach now that light-emitting diode (LED) fixtures can last for decades before replacement is required. They are installing light-transmitting ceiling panels (instead of opaque panels) beneath economical LED strip lights, thus creating luminous ceilings. Translucent and frosted panels create an even, diffused light that minimizes glare. The LEDs can be programmed to change colours to suit the mood of pool and spa parties or other events.
Light fixtures above pools and near pool decks need to be rated for wet or damp environments. In some jurisdictions, however, this requirement is waived if the fixtures are high enough above the water level. In these instances, putting the light fixtures above a luminous ceiling increases their height and may allow use of lower-cost fixtures rated for drier environments. A qualified engineer or electrician should be consulted before taking this approach.
