what would the be the best way to spray a catedral ceiling in a new addition. also the closed cell opened cell question altough
a discussion on this before here makes it pretty clear . we need to get the highest r possible . i know that by sealing it up tighter with srayfoam will help i still want to know if venting from top to bottom is enough and what if roof does someday leak?
need some answers quick this is actually in construction and even
the contractors are not sure as this is fairly new to them also.
