How to vent?


Attached are a couple pics of the 2nd floor in my garage. I want to vapor barrier and insulate with pink fiberglass but not sure of venting?? The framing was done prior to moving in. There are signs of moisture from the past, no mold and nothing wet right now and that is the reason for wanting to insulate. All walls are insulated and drywalled.

I grasp the concept of air movement behind the insulation... do I need to install a ridge cap vent (the kind that runs the entire peak of a roof) I ask that as I don't see how the air would vent without one??

There isn't any sorce of heat in the garage... Yet... But I'd like to throw in a pot belly stove for the heat. Not 24-7 just when I need to change the oil in the car or working on something.

Any help or suggestions would be appreciated. If more info is needed please ask. Thanks!!

I'm in south eastern Ontario Canada. All climate conditions apply.

You areas going to need R-50 in the attic. Your going to have to build those rafters out to be able to fit baffles and enough insulation.
It would be nice to also have a picture of the outside.

Is that 2x6 or 2x8?

Putting a baffle in those rafter is going to mean less than R-24 at best. That is going to such for insulation value in that area of the world. How much will you be using that space?

How to vent?


To answer all questions...

The rafters are 2x6 and where the walls are they are notched to 3.5".

As for use it's where we'll park are cars, I'll change their oil and odd projects here and there. Very minimal use. Like I said above a small pot belly stove to take the chill out of the air while doing whatever in there is all I want. I mainly need something because if I leave it I'll end up with all kinds of moisture problems.

Heres a couple zoomed in shots of the garage from other pics I had in my phone.
