FB Eaves Vent

  • The principle of cold attics and venting through eaves is very widespread and has worked very well since it was introduced.

    The principle ensures adequate venting of the roof structure and prevents fungal growth and other moisture damage, while keeping the roof surface cold to avoid undesirable consequential damage from snow melting and icing at eaves and gutters. But the principle has always been problematic during fire, because fires are spread to the ceiling and roof by flames breaking out through the window and up through the open air slots in the eaves. Fires that spread to cold ceilings often result in major material damage.

    80% of all fires spread between terraced apartments are due to the spread to the attic via the eaves and further to neighboring apartments.

    With the FB Eaves Vent, there is now a simple and safe solution available, which both meets the need for venting through the eaves while at the same time effectively preventing the spread of fire. The vent is approved for 30 minutes of fire resistance (EI 30) and thus satisfies the recommendations of fire cell limiting construction of eaves.

    For the construction of new buildings, this means that one can achieve satisfactory fire safety and still use the principle of cold roof and venting through eaves. For existing buildings with cold ceilings, sealing of the eaves and installing the Firebreather Eaves Vent is a suitable measure to achieve satisfactory fire safety without extensive building adaption.

    FB Eaves Vent is a completely passive product with no moving parts, detectors, wiring or activation.

    The vent has a patented set of metal elements that instantly prevent the penetration of flames.

    In addition, it contains intumescent material that expands when exposed to flames or hot gasses and completely seals the Eaves vent for the classified period.
