Photos of site-built ventilation baffles

Martin Holladay | Posted in General Questions on

For an upcoming article on site-built ventilation baffles — that is, baffles used to create ventilation channels under roof sheathing — I’m appealing to GBA readers to send me photos of your work.

You can post the photos here, or send them to me by e-mail: martin [at] greenbuildingadvisor [dot] com.

I’ve heard of builders making these baffles out of rigid foam, cardboard, plywood, and fiberboard. If you have a favorite material, including one I haven’t listed, please let me know about it.

    Baffles, or just intake/exhaust structures? For what purpose, sound
    deadening or water control or thermal breaks or ... ? Not quite
    understanding the question.
