Noiseflex® Pyramis PU / MH

Noiseflex® Pyramis PU / MH


Noiseflex® Pyramis are pyramid absorbers made of Basotect® or PU foam. 

The vibration of the air particles is converted into thermal energy by the pyramid-shaped surface and special pore structure of the pyramid absorber. 

This pyramid absorber has the property to shorten the reverberation enormously and to eliminate reflections.

Customer benefits

  • Achieves high absorption values and significantly
  • reduces reverberation times
  • As PU-foam the FMVSS 302 is fulfilled
  • B1 is fulfilled as MH foam
  • MH-version also available painted and flocked

Field of application

Noiseflex® MH offers a wide spectrum of attractive characteristics, e. g. it is highly sound absorbing and light weight. These acoustic advantages of Noiseflex® MH are behind the many applications of Noiseflex® Pyramis MH in the field, especially in sound studios, HiFi range, open plan offices, production and multipurpose halls as well as event venues. Noiseflex® Pyramis MH, if properly applied, is capable of drastically reducing sound level and reverberation time in halls, for instance.

Noiseflex® Pyramis PU open pore, cut polyurethane foam, especially for our sound absorption. Sound Insulation Absorber Pyramid particularly useful for: soundproofing lining in machines, gymnasiums, classrooms encapsulation or partial encapsulation covers such as metal boxes and caps soundproofing of pipes

Product Information

That sound absorption in rooms can be very important, is fact among acousticians. Noiseflex® Pyramis MH are pyramid shaped broadband absorbers made of Noiseflex® MH. They can produce an improvement of room acoustics mainly at medium and high frequencies. Noiseflex® MH is a flexible, open-cell foam material made from melamine resin. Its typical feature is the filigree, spatial network structure, which is formed by slim and thus easily ductile fillets.

Noiseflex® Pyramis PU is also in combination with bitumen board or for structure-borne noise reduction in buildings or industry suitable. This special, high class quality foam with a burning rate < 100 mm / min. respectively its automatically outgoing attribute according to FMVSS has a very good stability against weathering and a high imprint resistance.
