Ventilation
Passive Fire Products range of ventilation Fire protection.
Passive fire offer a range of ventilation fire products our range of duct sleeves offer up to 120 minutes’ fire resistance to all common PVC/plastic ventilation ducts.
We also offer a range of air transfer fire grille applications and plates. The resulting air grille can maintain ventilation within a building whilst also maintaining the fire rating of fire resistant elements for up to 1-hour Fire Resistance
Under normal conditions, the material offers a high level of free open area for excellent ventilation and air flow properties. However, in the event of a fire the intumescent material quickly expands to seal off the grille to provide an effective seal against fire and hot gases.
