Cape Cod ventilation conundrum
I’m turning one half of the upstairs of my dormered 1940s Cape Cod into a master bedroom and I’m just getting started on researching how best to bring the insulation up to code for Maryland (Zone 4). The area I’m focused on right now is the front cathedral ceiling, which is framed out with full dimension 2x6s.
I’ve found a ton of useful articles here on GBA (thank you!), including the one lamenting the difficulties of insulating capes. I’m aware capes don’t have soffits and so I was initially reading information about unvented insulation options, however, after removing the scant insulation from behind the knee wall, I noticed about a 1/8″ to 1/4″ open gap between the roof deck and top plate. The picture attached, though low quality, is how each bay appears. Does this tiny gap count as ventilation? Would it be an option to also consider vented assemblies?
Thanks in advance,
