It's been mid-December, and it feels like winter is at its best. Heating has become indispensable even in my room.

At the same time, it is the draft that is of concern. Even though the window key is closed, the cold air that flows in from somewhere ... I want to do something about it!

At that time, I found a 100-yen shop, Daiso's "gap tape." I would like to introduce this because it has had a non-stupid effect.

Daiso's clearance tape

A polyurethane sponge with a width of 1.5 cm and a thickness of 0.8 cm is sealed. The length of one product is about 5m.


It's a very primitive mechanism and doesn't even need to be explained, but to use it, just stick it so that it closes the closed gaps in the sliding doors and windows. You can cut the remainder with scissors.



That's all, but from the moment I put it on, I feel that the inflow of cold air has stopped. very! It's also good that the appearance is not noticeable at all.



If you block all of the top, bottom, left, and right, you will have a strong feeling, but the left and right alone will be effective enough (I think it depends on the building). I wondered if it would be okay to arrange how to paste it according to the shape of the gap, such as biting it into the door a little. By the way, one product is used up and it is about one side of the balcony window left and right + small window.


A crevice tape that improves heating efficiency and can be expected to cut electricity bills. It's a very analog method, but if you're worried about drafts, give it a try!
