PYROSORB

When selecting which PYROSORB product to use, it is worth considering in more detail what may at first appear obvious - namely, that the use of any sound absorption material depends on the particular application.

The frequency of the sound to be absorbed must be identified so that the method used to "engineer" the foam can be established to ensure optimum sound absorption.

For certain applications and frequency ranges, various facing materials can be applied to obtain a composite sound absorption material. To improve sound absorption even further, various thicknesses of PYROSORB may be bonded together - this can be particularly effective at the lower end of the frequency range.

PYROSORB Accoustic / Insulation Foams do not support combustion, melt or drip. Neither do they suffer wicking effects from contamination by dust or dirt. When a flame is applied, PYROSORB Foams simply char, leaving an inert char barrier that will protect other underlying materials from a wide range of ignition sources. When tested to B.S. 476 Parts 6 and 7, PYROSORB Foams achieve class 'O' to the British Building regulations.
