Cut-sheets
Ray Magic® QM (Quad Metal) panels are available with various perforation patterns to offer multiple looks and meet different acoustical attenuation derformance. Various custom patterns are available, the most common are illustrated below.
Perimeter moldings
The Ray Magic® QM panels are available with there different perimeter moldings:
Edge profiles
The Ray Magic® QM panels are available with four different edge profiles:
- Flat (15/16)
- Reveal 5/16 (15/16)
- Reveal 5/8 (15/16)
- Fineline (9/16)
Flat (15/16 grid)
The panels hang on top of a suspended grid made with 15/16′′ tees. The panels lip, carved and pared away, allows the tiles to go to slush conferring an even finishing look to the ceiling. The panels can be open giving access to the plenum.
Reveal 5/16 (15/16)
This panels have a bas-relief edges of 5/16′′ that rise up making a shadow between the panels.
Revel 5/8 (15/16 grid)
This panels have a bas-relied edges of 5/8′′ that rise up making a shadow between the panels.
Fineline (9/16 grid)
This panels hang on top of a suspended grid made with 9/16′′ omega-shaped tees. The lip of the panels is carved to allow the panel to slush and shade of the omega-shaped tees gives a refined finish look to the ceiling.
Thermal insulation (optional)
All Ray Magic® QM radiant ceiling panels can be ordered with an insulation mat above the panel (heat exchanger side) choosing from one of the following options.

Thermal performance
Thermal cooling capacity according to the normative EN 12040.
Specific cooling capacity refereed to the active panel surface (heat exchanger length multiplied by the panel width), in relation to the difference (∆T) between the room air temperature and cooling fluid mean temperature.
Thermal heating capacity according to the normative EN 14037.
Specific heating capacity refereed to the active panel surface (heat exchanger length multiplied by the panel width), in relation to the difference (∆T) between the heating fluid mean temperature and the room air temperature.

Thermal cooling performance tables

- hole diameter 1.8 mm
- regular hole direction
- perforated area 9.5%
- hole diameter 2 mm

Acoustical absorption coefficient
The surrounding surfaces (walls and floors) of commercial space are normally made with hard and resistant materials to facilitate cleaning and maintenance. This means that they reflect sound waves.
The acoustic absorption factor of the suspended ceiling becomes therefore very important to achieve a good acoustic comfort. The sound absorption properties depend not only on the intrinsic characteristics of the material, but also on the installation characteristics (ceiling void height) and on the final composition of the suspended ceiling.
Messana Ray Magic QM panels can be manufactured with custom perforation patterns with different perforation area and micro-hole diameters. The perforation patterns are design in a way that do not interfere with the heat exchanger installed in the back side of the panel. In this way there is not reduction of sound absorption.
Above the heat exchanger, besides the insulation, sound shields or other sound-absorbing materials can be inserted to further improve the acoustic characteristics of the radiant ceiling.
The graphic shows the sound absorption characteristics of a Ray Magic® QM panel perforated in a striped pattern (2′′ of perforated area alternated with 1′′ of blank space) with 2.5 mm diameter hole (approx 3/32′′). The perforation generates 16% of open area. The panels were covered with 30 mm of polyester fiber on the exchanger side. The drop ceiling was installed at 16′′ from the structural ceiling.
