Description of INTUMESCENT GRID Ventilodice EI60 minutes MODEL V40 :
VENTILODICE fire-resistant ventilation grills allow free circulation of air at room temperature through construction elements designed for fire resistance (walls, partitions, doors, etc.).
When the grates are subjected to fire, they swell with the mere effect of the heat, thus preventing the passage of flames, smoke and gases.
Ventilodice intumescent grids are activated at low temperatures (from 100º). When the grates come into contact with the fire, they expand due to the effect of the heat, obstructing the passage of flames, smoke and gases.
