Pyrok intumescent fireproof ventilation grilles are designed to protect air ducts in case of fire. During regular use, they allow free air circulation inside the rooms. During fire, the system creates a special barrier that prevents the flow of fire, smoke and harmful gases. The material Pyrok grilles are made of intumesces as a result of a reaction to high temperature and fills gaps in the grilles, which closes the flow of air and smoke and also insulates the heat flow. Intumescent surface is non-flammable. Under normal conditions of use, the air flow through the grille is not blocked.

• Fire protection of ventilation systems and air ducts
• Fire protection of ventilation systems through doors and walls where it is required to achieve appropriate fire resistance of the partition
• Fire protection of smoke control and odor removal systems that may be exposed to fire
