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.

Easy and Quick to Install
1. It sticks to the door easily, and is super easy to trim to size. Just peel and stick. Until pressed into place permanently, it's easy to pull off to make corrections(Just make sure to clean the surface before applying!)
2.Stay in place well as you open and close the door. BUT please remember not to open the door constantly within 24 hours after installation.
3. It is suitable for all standard doors & any room décor. The seal works with all types of doors, including exterior doors, interior doors, garage doors, roll-up doors, hinged wooden doors, and walk-through doors.

ATTENTION
There is also a bag of nails in the package, just using it when needed.(PS: ONLY use nails for tight it on under your door when the surface is uneven)
