The Benefits of Door Drop Seal.

A door drop seal is a device that lowers automatically when the door is closed,
creating a tight seal between the door and the floor.

A door drop seal has many benefits, such as:

◆It prevents noise, dust, smoke, insects, and drafts from entering or leaving the room through the gap under the door.
This can improve the comfort, privacy, and hygiene of the room.

◆It reduces heat loss or gains through the door, lowering energy consumption and heating or cooling costs.
This can also help maintain a consistent room temperature and humidity level.

◆It enhances the fire resistance and smoke containment of the door,
which can increase the safety and protection of the occupants and property in the event of a fire.
