Editor's Pick: That gap under the door looks like no big deal, but in winter cold air sneaks in, and in summer the AC leaks out. This silicone strip is soft and flexible, won't scratch your floors when applied, and you just cut it to your door width, peel off the backing, and stick it on. The three-layer design blocks dust and reduces noise, muffling hallway footsteps and outside sounds. Works on glass doors, sliding doors, and wood doors.
