Anyone know of a good article on how to spray foam the attic “floor” to create a vented, unconditioned attic?
I have been looking for a how-to guide on the ins and outs of spray foaming the floor of an unconditioned. Attic. I have found a great article from fine homebuilding 2009 by Michael Chandler, but it only covers how to create a conditioned (unvented) attic. I want my attic to have foam between/over the joists w/ baffles at the edges connecting to the soffit (a vented attic), but I haven’t been able to find a decent, detailed resource on how to do this. Anyone have any ideas?
