Description & use
Piro Intumescent Grille is a fireproof ventilation grille 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 toxic gases. The intumescent tape inside Piro Intumescent Grille as a result of a reaction to high temperature fills gaps in grille and closes the flow of air and smoke and also insulates the heat flow. Intumescent tape is non-flammable. Under normal conditions of use, the air flow through Piro Intumescent Grille is not blocked.
Piro Intumescent Grille is intended for:
• 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
Grilles are also
meant to be
apertures in plasterboards.
Combining grilles (side view)
Bend these pieces backwards and put them into holes located in a second grille in order to merge them together.
This method will allow to build custom shapes of Piro Intumescent Grilles.
