[Greenbuilding] Dryer vent backdraft solutions

[Rob Dickinson]

I'm curious what people like for backdraft protection for exterior dryer
vents

I've seen some positive reviews about the Heartland Dryer Vent Closure --
see the following link -- and would be curious if anyone on this list has
experience with it.   See:
http://www.amazon.com/HEARTLAND-21000-Dryer-Vent-Closure/dp/B00009W3I4

I've also read the marketing info on the Tamarack Technologies (
www.tamtech.com) Cape Backdraft Damper, which seems like a good idea and
well designed product.  See:
http://www.tamtech.com/store/one-way-air-flow-valve-6-duct,Product.asp

Seiho Intl. makes high quality dryer vents with backdraft dampers, but I
have no idea how effective the backdraft protection is.  I would much rather
have an ugly vent that really prevented backdrafts than a beautiful one that
only works ok.

Any ideas or suggestions welcome.
