How would you insulate this overhead door opening?

reddit.comYou can try vapour barrier (the thick stuff used inside the insulation houses) and install job site tape on zippers. A roll of vapour barrier, a set of zippers and a roll of proper tape to hold the zippers on. If you stop air flow the 4inchs of air between door and plastic will act as an insulator.

Thank you for taking the time to post this. I did this with 6mm plastic vapor barrier and the dust zippers you suggested. Glued it to the concrete with construction adhesive. Working great so far, thanks again.

Awesome! Not a problem. I am very glad I could help. I knew once you could stop the draft the air gap would be a fine insulator. Cheers.

This is a door between a covered/closed-in parking garage (unheated) and a heated kitchen. It's used for a mobile food cart so that the cart can be stored in the heated kitchen/prep space.
It leaks a ton of cold air in the winter. I'd like to come up with something that can easily be removed and replaced twice a day.
My current thoughts are to get some 4x8' sheets of extruded polystyrene 1.5" thick, cut to size and layer them 3 or 4 deep. Bond together with glue and/or lags. They would be just the right size that you'd fit it in there like a puzzle piece. Maybe add some handles on one side.
Other ideas?

We bought big ones of these and just lean them against the door. A rope to keep them from falling back. Works well for cheap, simple, and ready to move out of the way when we need the door.

Sheet of glass plastic and use flashing tape all the way around so it’s airtight.

This isn't supposed to be an issue at all. Do you still need the door? A wall will work better. But if not, It's pretty simple to insulate this, I think.
Products like these do the job.

Do you still need to open it?
Yes.
