Okay got the vent plugged thanks to the wifey.
Figured I might as well show my first attempt at a air vent, open to suggestions.
I’m going to leave it for this winter but definitely going to do something different next year.
So left is intake right is exhaust.
2 pieces of Styrofoam insulation cut to size and glued together with thinner weather stripping around the bottom and side edges followed by a larger piece of weather stripping layed ontop where the window meets the Styrofoam.
I then found this cool sealer stuff and sprayed it on the outside facing board but it melted the foam a bit in exchange for hardening it up and covering it with some sort of hard liquid rubber… Oops.
The wifey pulled the intake off and stuffed it full with some hand towels for now before putting a plastic bag on it.
I’ll do something else when I get home.
Unfortunately I couldn’t use that nice dense pink foam board because it didn’t come in the right thickness or half the thickness and thus I wouldn’t be able to slide it smoothly into the grove of the window.
I have enough to re do the Styrofoam again, when I do the one thing I can think of is putting a piece of poly on the outside, and if I ever need an intake again I will use insulated ducting hose due to the condensation I was seeing beginning to build
