There are always gaps between the door and the floor. The rain, wind, leaves, snow can blow in your home easily by the gap. The door seal is a great addition to close the gap between the door and a sloping driveway or uneven floor.

From an energy efficiency perspective, door seals are aiming to do two things:
1.Seal the door (minimize unwanted air leakage and ingress of bad weather)
2.Improve the door's insulation value (cold air can't get out from the room as well as the hot air can't easily get out of the room.)

From a comfortable living environment perspective, under door draft stopper can also do:

1. Windproof & Waterproof. It helps further from drafts & excess sand coming in. This seal will prevent leaves, dirt, water, and snow from blowing under your door.
2.Soundproof. It reduces the noise level from outside, and vice versa. Get a quiet & private space when you tell your phone conversations or stay alone.
