Best Way To Seal An Interior Door

[Michiganja Meduana]

I need to deal with an inside door that is allowing light, and air past its frame. I was wondering the best way to stop this.

Does the door open in or out? Either way, glue or tape 3"-4" wide piece of sturdy cloth (or other dark non see through material) to the door it self so there is enough to overlap the gap. Then you can open and close the door without disturbance.

My 2 cents. I did a test run a completely flowered a plant in a shady corner of a room. It did not have direct light on it but there were lights on near by. The plant knew when it was put under the hps that its day time and when it went to the corner it ws night time. It turned out great. no stress or nanners.

Opens toward you. I'm not so worried about nanners, (I am really) but the door is in the living room, and the light is just blazing behind the door jamb.

I was thinking that a curtain held shut with a tent zipper might do the trick.

You could staple an inch-wide piece of cardboard on the door stop portion of the jamb (on the thin side that the door stops at) parallel to the door. That'll stop leaks from the sides and top. Then perhaps either a sweep at the bottom, or a towel laid on the floor.

I'd like to stop all air leaks as well.

around the door, use weather stripping. about 3.00 for a 1/2 x 10' piece. use it like a gasket so when the door closes, it seals any gaps. like for windows before winter time.

This is what I do around my door. Cheap and works perfect!

Use the foam sheets up to 2 inch thick will block light and air flow in any window or door.

buy a decent rubber door sweep for the bottom and do weather stripping on all the other door seams (don't forget the back seam, the one with the hinges) and you'll be golden for light, airflow, and noise. (I have applied this combo, it made a big difference.) Just look at any exterior door, which is a situation where total airflow stoppage is critical for keeping heat... this is how it's done.

I thought about just installing an exterior door.

An exterior door only works because of a large door jam. The piece runs around sides and top, creats an air/light tight space. Some cheaper doors, or older doors may have shifty jam, and you could easy increase the jam size, or find a door jam seal, it usually comes in a roll, and is foam or other materials, and you peel off the backing and apply like a sticker.

It is a door sweep and weather stripping (the stuff Bomixius is referring to, the "door jam seal") that makes an exterior door effective anyway. You'd end up needing to add those to the exterior door to make it air tight as well. If you add them to an interior door you will simulate an exterior door at much less cost and effort.

That makes sense.
