what is bottom drop seal and what are its uses

A drop seal is a device used to create a seal between the bottom of a door and the floor, preventing the passage of air, smoke, and sound. It is typically made of a flexible material, such as silicone or neoprene, epdm rubber with aluminium profiles that can be compressed when the door is closed, and then springs back into shape when the door is opened.

Drop seals are commonly used in commercial and residential buildings to improve energy efficiency, reduce noise transmission, and prevent the spread of smoke during a fire. By creating a tight seal between the door and the floor, drop seals can help prevent drafts and air leaks that can cause heating and cooling systems to work harder and waste energy.

In addition, drop seals can help reduce noise transmission between rooms by blocking sound waves that would otherwise pass through the gap between the door and the floor. This is especially important in environments where noise levels need to be controlled, such as offices, hospitals, and schools.

Finally, drop seals can be used in fire rated doors to prevent the spread of smoke during a fire. Like smoke seals, drop seals help contain smoke to the area where the fire originated, giving people more time to evacuate and reducing the damage caused by smoke.

Overall, drop seals are an important component of building design and can help improve energy efficiency, reduce noise transmission, and enhance fire safety.

It is also main part in case of sound proof doors where sound and air and smoke is stopped by putting bottom drop seals on the bottom of doors and when door is closed than this seal cover the total gap between door and floor and when we move the doors due to pressure button get push by outerframe .Then it get setteled to upside and get down and cover bottom when door get settled at its place or door get locked or closed.For more blogs click on
