Freely suspended Rigitone ceiling for even better acoustic comfort

Freely suspended Rigitone ceiling for even better acoustic comfort

The free-hanging Rigitone Islands excel in their interesting and unique design. Thanks to their easy and quick assembly, they can be used especially in the reconstruction of a space with poor speech intelligibility. They are basically delivered in the color of natural cardboard, ready to be hung. However, you can paint them with any shade.

With the right paint color chosen, the absorber will reflect light around the room exactly as needed for the room. You can add ceiling lights or spot lighting to the absorber. "The maximum additional load corresponds to 1.5 kg per anchor point, in total the weight of the additional loads should not exceed 3 kg per m 2 of the ceiling," adds Vojtěch Zítek, Rigips product manager.

Absorbers that you will especially appreciate in the office

More people in a small space, frequent phone calls and difficult concentration. Situations that we all know for sure and that often affect our work performance. It was similar in the area of ​​two Prague offices, where two to four people work at once. The moment the phone rang for all of them and everyone started talking, the space became almost uninhabitable. The reason was the reverberation time. It was around the upper recommended limit for the office. There were simply too many sound waves left in the room that could not be swallowed in time. This led to a difficult concentration of employees and the so-called Lombard effect arose in the room. This is basically a situation where one person shouts at another in an effort to increase the intelligibility of their word.

"After the installation of the Rigitone super absorbers, the situation immediately improved, when the total noise level in the above-mentioned situation decreased by up to 5 dB. If we consider that 'a change of only 3 dB = double', this is a great success in the field of acoustics and the quality of the working environment, "explains Vojtěch Zítek.

Why is room acoustics to be addressed?

Improperly designed or unresolved room acoustics is a frequent reason for increased human fatigue and impaired attention, which can lead to reduced human performance not only at work.

The most well-known criterion of room acoustics is the reverberation time. The longer the reverberation, the longer we hear the sound in the room; the room has a long reverberation. If it is too short, the space is dimmed and we do not hear the sound clearly enough. It is therefore necessary to pay attention to the correct placement and shape of the absorbing and reflective surfaces in the room. Rigitone absorbers are an ideal solution even in those areas where the acoustics have been completely forgotten and need to be addressed additionally and quickly. The absorbers are available in two variants - with mineral and without mineral insulation (see table below). They differ mainly in their sound absorption. If you are interested in other ways to solve the room acoustics of your project, see all Rigips solutions for room acoustics.

Advantages of the suspended island Rigitone:

You will certainly appreciate the easy maintenance. The boards can be cleaned with a vacuum cleaner or a damp cloth (damp sponge). In the event of heavy surface contamination, you can proceed with the renovation with a new plasterboard coating. This extends the overall life of the material, reaching the life of the entire building.

How does the assembly work?

Rigitone free-hanging absorbers have the advantage of being suspended at only 4 points using metal anchors. The supporting structure is part of the absorber, which significantly simplifies and speeds up the entire assembly.

Before starting the installation, it is necessary to think carefully and focus the position of the absorber. We are looking for 4 places where we will hang the absorber using a metal element (molly anchor, FN screw, steel ceiling nail). After aligning the anchor points, we attach wires with an eye to the ceiling structure using a suitable anchoring element.

We fit four-point hinges into the CD profile inside the absorber by turning them in the profile. The mineral insulation is already in place, however, we will check its settlement inside the absorber to be sure. Then we hang the whole absorber on pre-prepared wires. The absorber can be used without paint, thus leaving it with a more industrial appearance. If we want to paint the absorber, we can start immediately. We need a color suitable for plasterboard (any shade), penetration and a roller with short hair. After applying and drying the penetration, we apply the paint as standard in two layers according to the manufacturer's instructions.

Clean air as a bonus

Rigitone absorbers have Activ'Air ® technology. "It reduces the concentration of formaldehyde in the indoor air by up to 70% for 50 years. To achieve maximum efficiency, it is advisable to use at least 1 m 2 of boards per 1 m 3 of room, "describes Vojtěch Zítek technology. Gypsum is also a material that helps regulate humidity. It absorbs and removes excess moisture, thus alleviating microclimate changes and protecting human health. The material is naturally healthy.
