We have vents on the second floor of an old post and beam cape in NH. These actually vent the cold air side of the kneewall. There was flow through vents at either gable end but a recent addition on one of the gable ends required removal of the vent. The kneewalls are insulated and the floor but the roof slopes are not. Now that there is only one vent for this space, should it be closed off or should we find an outlet to restore the flow of air behind the kneewall.

I'm not sure of the best answer here, but I've seen little attic spaces like this behind knee-walls get vented right through the roof within that tiny little attic space, there are roof vents that can be installed and shingles can be patched back in around them.
I guess what would probably determine if you need to do this (continue venting that space that is), is if that space was functioning as the outlet end of soffit vents below, or if the gable vents were allowing air into the space which then traveled up between the rafters, over the interior living space to a ridge vent on the roof? As you look at the insulation in the kneewalls, when you get up to the rafters, is there and air space over the insulation?
i'm wondering how there can be more than one bud on this board.i noticed it a month or so ago someone asking questions with my screen name but figured it was a prospero thing but now?again
bud, we could all be buds if we wanted too - - duplicate nicknames are fine with despairo...
No the post and beam bents are about on 9 ft centers. the living area walls and ceilings are either blown in or fiberglass but there is no way for air to move up the roof deck to any kind of a ridge vent. The roof is standing seam. Thus the vents (aluminum ) are or I should say were, venting only the space between the kneewall and the soffits (no soffit vents either) I can get into this space via an access door and it's cold in there!!!
