Convoluted foam, the versatile acoustics product

The convoluted foam is a sound absorber with an extremely enlarged surface structure. Its wavy surface makes it an excellent broadband sound absorber. The convoluted foam is a fine-pored, flexible polyurethane foam with an open structure that is permeable to air. It is a very effective sound absorber.

Frequently asked questions (FAQ)

Basically, neither pyramid foams nor nubbed foams are suitable for sound insulation to the outside. These two sound insulation materials mainly reduce noise or reverberation in rooms and are used to absorb sound. Above all, the room acoustics are improved. The nubbly foam as well as our pyramid foam are produced "swiss made" in the Vibraplast AG. The pyramids are produced by cross-cutting on a horizontal contour cutting machine, the nubs are produced with a profiling roller. Since the production of pyramid foam takes longer, the price is correspondingly higher than that of nubbed foam. The panel thickness defines which frequencies are absorbed. The thickness of the foam defines which frequencies are absorbed. Thin foam boards tend to absorb in the higher frequency range, while thicker foam boards tend to absorb in the lower frequency range. For the same material thickness, nubbed and pyramid foams are equivalent. It is up to you to decide which look suits which room better.
In general, the thicker the foam, the better and more efficient the sound absorption. If mainly middle or higher frequencies have to be optimized, good results can be achieved already from a thickness of about 30 mm. If low frequencies (bass tones) are involved, thicknesses from approx. 50 mm are advantageous. In general, it should be noted that the lower the frequencies and the higher the room, the thicker the foam panels should be. If a material is too thin, it only absorbs treble. If the material is thicker, it also absorbs low frequencies
In general, it can be said that the more surface of walls and ceiling is covered with foam materials, the less sound can be reflected from them. From experience, it can be assumed that approx. 40% - 50% of the ceiling and wall surfaces should be covered. With 100% cladding there is no more natural sound and this leads to unpleasant acoustics.
Various factors can influence the room acoustics. For example, organic materials such as cork floors, wooden parquet, wooden ceilings or wooden walls are very well suited for pleasant room acoustics. Smooth concrete walls, granite floors and glass surfaces reflect sound very strongly and as a result are acoustically unfavourable. The interior design has a great influence on the sound spreading and as a result on the sound image in the room. A lounge seating area or a fitted carpet has an absorbing effect and a book shelf on the wall ensures that the sound is diffused. However, a specific improvement of the room acoustics can only be achieved by combining special Silphon acoustic modules.
The foam standard boards are delivered as untrimmed raw boards. The ordered useful dimensions are guaranteed, protruding material (foam, fleece, SK-foil ecc.) is but possible."
Acoustic foams which have the fire protection class FMVSS 302 are mainly used in vehicle and machine construction. By adding flame retardant to the foam, the speed of flame propagation in case of fire is reduced. (4 inch/minute) The test method introduced in the USA as the Federal Motor Vehicle Safety Standard (FMVSS 302) is used by most of the world's automobile manufacturers.
