Feltfon Baffles

OVERSIZED LINEAR BEAMS for superb sound absorbing

Feltfon© Acoustic Baffles enables the incorporation of large design elements in significant dimensions, maintaining a lightweight and cost-effective solution. The utilization of absorbent felt material and the presence of a hollow core in Feltfon© Baffles contribute to excellent sound absorption. The Capax Quick-Up installation system is available for walls and ceilings, perfect for use in public spaces like schools, offices, shops, and malls. Approved for use in wet rooms. The installation system grips multiple baffle widths and is fully demountable. Create a unique appearance by varying and combining different widths, depths, felt colours, or the width of the spacings. Of course, Feltfon© Baffles are fire-safe – in the Gustafs way, without the need for impregnations. Made from a minimum of 50% post-consumer recycled content. The Feltfon acoustic ceiling baffles help reduce sound waves and sound-proofing the room.

Acoustic Ceiling Baffles – how do they work?

Reducing sound waves
+

Sound Baffles are acoustic panels that are suspended vertically from the ceiling or, if you like, installed on the wall.
Acoustic Baffles can be very effective, reducing sound waves, in open-plan spaces such as offices, schools, and entrances, where they can help prevent propagation of sound over longer distances. In addition, their sound-absorbing properties can help to reduce reverberation and overall sound levels, creating a more comfortable environment.

 

Why use Sound Baffles?

... and why are they so effective?
+

Acoustic baffle beams helps reduce sound in large spaces with high ceilings. Ceiling Baffles provide a larger absorptive surface area, is very easy to install, and is available in many depths and dimensions. In many public spaces it is common to encounter a ceiling made of steel decking or concrete – materials that are highly reflective and don’t absorb sound well. As sound travels towards the ceilings, it will encounter these highly reflective surfaces which only absorb a very small amount of sound energy. The sound wave will continue travelling within the room. Acoustic ceiling baffles are particularly effective for sound proofing a room as they can absorb both the direct sound from a sound source, and the reflections from ceilings and higher sections of the walls.

Mix dimensions freely

By mixing dimensions freely, you can achieve an exciting and personal expression on your wall or ceiling. The only limit is your creativity.

Dimensions

A wide range of standard dimensions let you design your acoustic ceiling freely.

Spacing

Spacings using the Gustafs Quick-Up Capax System: 22 mm, 53 mm, 84 mm, 115 mm, 146 mm, 177 mm, 208 mm, etc.

Easy to join with no visible seams

The baffles are easy to join end to end without visible connections or install baffle by baffle with gaps.
