Soundproofing Foam: Class O

Sound Zero Class O foam (soundproofing foam) is a modified, flexible open-celled polyurethane foam that is treated after it has been cut into sheet form to add extra density (mass), as well as a fire-retardant additive to make it construction ready, achieving the highest fire-rating possible. No other soundproofing product is in the same

Used as an acoustic sound absorber, Class O foam is a high mass acoustic panel that offers unparalleled sound absorption across the full frequency spectrum, especially in the troublesome low frequencies range.

No other acoustic product on the market matches up to the same level of absorption whilst achieving the highest possible fire resistance ratings for a flexible acoustic foam. It is a chemically inert product that will not crumble even when subjected to high-velocity airflow, making it the ideal choice for HVAC soundproofing.

With its open celled structure and high-density level, Class O foam makes for the ideal use in the application of soundproofing rooms. This is a highly fire resistant and flexible type of soundproofing foam, which is completely safe to handle, can be easily cut on site without causing airborne debris and the need for a face mask, eliminating any potential health concerns one may have regarding a link to fibrous materials.

Being semi-rigid, it is far easier and quicker to install than the more common, fibrous wool insulation, saving time and money on labour costs.

For those wishing to equip their office meeting rooms or their recording studio with soundproofing, highly fire-retardant foam, Sound Zero Class O foam is the only choice.
