Eaves Vents positive ingress
by Isa Stralian
Conclusive research by Condor Kinetic shows that efficient roof ventilation is dictated by air ingress.
Air ingress at eaves is important
Having a fan on the roof to extract the hot air out is not the best approach especially when considering that all roof items on a building require periodical inspection and having a motorised fan at the top of the roof is both impractical and inefficient.
The reality is that electric motors operating above 60 degrees will have an early failure rate.
And reason being that electric motor manufacturers will not guarantee operation above 60 degrees
The average internal temperature at the top of a roof is 68 degrees so considering the cost of contract maintenance, cleaning and or replacement, it is best to keep all in easy access, and no higher than need be.
Whether the roof ventilator be passive or powered, the air ingress via the eaves vents dictates overall efficiency.
So it makes sense for the ingress at the eaves to be powered, and not the egress, particularly when it comes to roof ventilation.
Using a Condor I&E Series Eaves Vent makes sense because it’s important to have a positive ingress of ambient cool air into the roof cavity and allow pressure to push out the hot air out of a passive vent at the top.
The Condor I&E Series Eaves Vents provide the air ingress necessary to maximise and improve the flow through in the roof attic area, and it can be speed/ flow controlled.
Available in solar powered 12vdc or 240vac, the Condor IE eaves vent will fit all eaves, however keeping in mind that the heat purge cycle is in the evening so whatever you install has to function of an evening and solar will not do it.
The design of the eaves vent is also critical particularly in BAL criteria applying to those areas prone to high fire risk.
