ODE NFAF PROMESH APPLICATION AREAS
 |
Ventilation Ducts
ODE NFAF is a high performance fire proof acoustic foam that does not cause fiber erosion in ventilation ducts. It can easily be applied to interior parts of ducts with its original liquid adhesive. |
 |
Generator and Broiler Cabins
ODE NFAF is the ideal sound absorbing material for generators and broiler cabins. As there is no risk of flammability, it can securely be used in such environments. |
 |
Studio and Movie Theatres
ODE NFAF can be used for volume acoustic arrangements in movie theaters and studios. As it carries no risk of flammability it can be used securely. It can also be used in places such as restaurants and bars that are open to the public. |
