How to stop cold air from cellar door

Finished basement room where cold cellar is located seems colder than the other rooms. We tried weather striping the gaps but still feel that cold air is coming from cold cellar! How can I insulate that door so that room will be warmer? Can covering the door with plastic film or covering the door with bubble wrap will help.

Door sweep? Install rubber weatherstripping?

If you really want to stop the door from feeling cold to the touch you could glue a 1" piece of Styrofoam to the door. It won't be pretty but it will work.

Is it an interior door? If so, replace with an insulated exterior door.

I think you need to replace the door with an exterior door.

Is the cold cellar vented to the outside? If so, it should be an exterior grade door.

If the vent is plugged (sometimes people do this), an interior door is ok.

1) Weatherstrip on both sides of the door.
2) Change the door.

My cold cellar checked in at -4°C a couple days ago when we had that cold spell. There's a vent hole (about 4" in diameter) at the top of one wall.

With the door (standard cheap door that the builder put in) closed ... I don't feel the draft coming in to my unfinished basement. I guess it's because the weatherstrip at the bottom is done well enough.
Stress is caused by NOT fishing enough.

Doors and windows are typically the weakest links when it comes to the insulating factor of the wall. As others have said, ensuring that the door is exterior rated and weather stripping that door will be two courses of action. You may also want to check that the door opening is properly insulated and sealed to the door frame -

The door sweep is usually the falling down point.
Gbill2004: Thanks but I'll just smell the couch before/if I buy it.

jonnyb: I go in there like PICASSO and toss the glue everywhere, I don't care what house I'm on.

That’s what I used last year. I used P&L and stuck on door exposed to cold room. Combine that with gap insulation, it kept the home interior from the cold.

I am going to get this weather stripping tape https://www.homedepot.ca/en/home/p.flex ... 20747.html and try to fill some gaps between the door frame and door and see how it works.

Where did you get styrofoam sheet? And what is P&L-sorry, I didn't get it.

Thanks.

Door sweep seems fine-it is plastic one and no space to attach door snake shown in photo.

Still will try to put a pillow or some homemade thick door snake to stop cold air. Thanks.

Lepage Premium PL. Can find it anywhere include HD. You can get the Styrofoam from HD or Lowes or any 'respectable' hardware store. Either pink or blue.
