Show us your window box/closures

[forknowledge]

Im done with growing in a cab & now its time to move up a gear, all is planned out for the grow room however the only issue Im having problems with is sealing up the window which will be the intake, Id like to seal it up using a combination of insulation board (so the FLIR cams cant pick up any heat signatures), light tight film (for an extra precaution), plywood (for a sure seal) & blinds in face of the window to prevent pass byers from seeing anything although Im worried this may restrict airflow . The challenge is to construct it in such away that it makes as little damage as possible when attaching it to the wall plus there needs to be an opening/closing hole to enable opening & closing of the window itself.

Id like to see the your window boxes just so I can pick & get ideas to get it done correctly the first time so your pics fellas.

walmart blackout curtain thumbtacked around the window frame.
1 isn't enough but 2 should be.
Looks normal enough from the outside I'd say.
As long as you keep air sucking out of the room (neg pressure) the curtain will stay fluffed and allow air to be pulled in.
Not a great idea though if power should go out for any amount of time and the smell
starts to waft out of that open window though..
