Seal foam attic baffles at kneewall
I am installing the foam version of the attic ventilation baffle at my kneewalls so that I can blow in a good amount of cellulose. The online video from the manufacturer shows them simply hammer-stapling these along the trusses. Two things I notice, 1.) These things rattle like nothing else when air is coming from my vented soffit at the right speed/angle because there is nothing pinning these tight to the underside of my roof’s OSB (ideally I’ll have enough insulation to keep them somewhat tight) but I don’t think it’ll be *that* deep. 2.) These have visible holes where they fold down from top plate of wall to the angle of my roof. I’m just using spray foam to fill the voids and cracks or damaged pieces…any other suggestions? The foam appears to stick well once hardened.
