Ventilated Fire Stopping
The INCA WFS net® Vents is a new and safe fire sealing system for ventilated openings where air movement is needed from the outset, but where a completely sealed structure (EI) is immediately desired in the event of a fire
If a fire takes hold in a building then the ventilation shafts and openings provide an ideal opportunity for the fire to travel between rooms and also to outside areas. The Inca WFS net Fire Suppression for vents is a new and safe fire sealing system which halts this progress. It is suitable for applications where air movement is needed, but where a completely tight construction (EI) is immediately desired in the event of a fire.
The system is fire tested and classified with fire class EI 30 / EI 45 according to the latest standards (EN 1366-4:2021, EN 13501-2:2016).
The INCA WFS net® fire network is easy to retrofit and suitable for most ventilated fire stopping applications!

Product Description
Fire class EI45 – Type approved
The INCA WFS net® fire network is a new and safe fire sealing system with fire class EI 45. It is ideal for applications where air movement is needed in the initial position, but where a completely sealed structure (EI) is immediately desired in the event of fire.
Easy to assemble
The system is easy to assemble and consists of a high-performance fire-swelling metal mesh which ensures the necessary ventilation of the air gap.
The INCA WFS net® fire network operates with maximum function without the risk of fire spreading above the fire limit created. In the event of a fire, stick flames, sparks and heat get trapped in the fire-swelling network. At 150°C, the material begins to expand (50 times its own thickness) and quickly seals the openings of the net, preventing extensive fire spread.
Retrofit
With the INCA WFS net® fire network, installation is smooth and easy.
Best construction economy
The INCA WFS net® fire network is the fire protection solution with fire class EI that provides the absolute best construction economy.
