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.

For clarification on minimum requirements before buying one of our fire-stopping products, please review the information. A written specification should be obtained from our Technical Department for your project prior to use to ensure the product will be suitable.
