Hurricane resistant vent design
« on: June 04, 2012, 08:33:35 PM »
I've read on the State of Florida Emergency Preparedness web site that roof vents can become locations where wind-driven water can enter buildings during a hurricane.  While this applies to all types of roof vents such as peak vents, and powered ventilation hoods, it also is relevant to dryer vents.  Until reviewing the You-Tube videos on your company's website, I expected to modify the vent for my dryer to use an eve vent.  The only practical means I know of to reduce water intrusion in a high wind condition is to fabricate a cover for the opening on a gooseneck vent that can be secured quickly just before the storm.  Are there any codes that address this need?  Are there any products that can survive a hurricane that are water intrustion resistant?

Rick, good post, and thanks. 
I agree, the best option is to install some sort of "block" or cover that would act as a primary blockage to wind driven water.  The Dryerjack Zero has an opening about 6" x 4".  If there was enough call for it, we could create a metal cover that would hook on the hem and be supported by the PacMan mouth area, but you are the first to inquire about this.  A workaround would be to cut a piece of plywood or metal that would fill or block that opening, maybe securing it with a sheet metal screw.  And then create some sort of reminder tag that you would place over the control knob on the dryer that would prevent a user from turning it on until the "cover" was removed. 

There are no codes that address water intrusion from roof vents.  I will try some wind testing on the zero soon to see if and how wind could lift the damper.  I feel if the damper would stay closed, water intrusion from wind driven would be minimal enough to not cause siginificant damage. 

Keep me posted on any other findings.  Thanks

It is a very good idea I like.
