Rockfon - Eclipse

Rockfon Eclipse is an acoustic island made of a 40mm thick stone wool panel. The visible side is covered with a painted glass fleece creating a nice smooth white surface. The back side of the island is covered with a white acoustical fleece providing excellent light and heat reflection. The edges are painted.

Rockfon Eclipse is an innovative acoustic island which offers new opportunities for correcting acoustics while bringing a whole new aesthetical dimension to the room. It can be used alone when a traditional suspended ceiling cannot be used (glass roof, historical buildings...) or as a complement to an existing ceiling for retrofitting purposes.

Frameless, trendy and stylish, Rockfon Eclipse is available in various of shapes in order to bring a solution to any kind of room configuration. The square and rectangular shapes feature a sharp edge underlined by a subtle and elegant bevel. All other shapes come with a minimalistic straight edge. Its smooth white surface is very long-lasting and ensures a perfect energy-saving reflection of light and heat. Suspension accessories were also developed with design in mind. Modern and very discreet, they give the impression that the islands are floating in mid-air.

Just like every other ROCKFON solution, Rockfon Eclipse offers the highest performance in sound absorption and contributes to reducing reverberation time and ambient sound level. Rockfon Eclipse therefore enables rooms to reach the optimal level of acoustic comfort. Sound absorption is optimised thanks to the islands absorbing on both sides. Rockfon Eclipse also enables acoustic correction in premises using thermal mass by enabling the air to flow freely in the room.

Technical Data

Sound absorption

Aeq (m2/item) - The sound absorption property of islands and baffles is quantified using the equivalent sound absorption area Aeq expressed as m2 per item. The Aeq value is measured in accordance with the . This is the area of a fictive absorbing surface of αw = 1.00 which would absorb the same amount of sound as the tested island or baffle.

Light reflection

Front side: 86%
Rear side: 79%

Light reflection expressed in % is measured in accordance with ISO 7724-2. The backside of the island is white in order to guarantee optimal light and heat reflection.

Reaction to fire

Class A1
Rectangle 2360 only: Class A2-s1,d0

Reaction to fire is classified in accordance with EN 13501-1. The fire protection properties of ROCKFON ceilings have been tested and classified in accordance with European norm EN 13501-2 and/or national norms depending on requirements in national building codes.

Humidity and sag resistance

Up to 100% RH
Corrosion resistance of spiral anchors: Stainless steel type 1.4401 (grade 316) suitable for class C3 areas.

Rockfon Eclipse is dimensionally stable even at humidity levels of up to 100% RH and can be installed at all temperatures ranging from 0ºC to 40°C. No acclimatisation is necessary.

Corrosion resistance: The spiral anchors used to fix Rockfon Eclipse consist of stainless steel type 1.4401 (grade 316) which offers an extra high resistance to corrosion under normal conditions and are suitable for application in class C3 areas (EN-ISO 12944-2). This type of stainless steel is typically used in food processing or brewery equipments, chemical and petrochemical industries, laboratory benches & equipment, medical implants. Rockfon Eclipse should not be used in swimming pools or outdoors.
