Well, that was probably nothing! This insulating tape is not against draughts - these usually come through a small gap. However, this actually quite clever sealing device is only useful if you accept that you can no longer close the door afterwards, because the thick foam no longer allows the door to be closed properly. After pushing against it with all your might (only after cutting the outer foam sausage in half) it works, but of course this creates a gap elsewhere, which is not really the point! So maybe this tape is something for barn doors, but nothing for (or against) a draught gap in the living area. 2 stars nevertheless, as the pre-order worked quickly and well.
Is tight
Very good
