Do drop down seals stop draughts?

Yes, drop-down door seals are designed to help prevent draughts by creating a seal between the bottom of the door and the floor when the door is closed. By helping to block the passage of cold air, drop-down seals can reduce unwanted draughts, improve comfort and contribute to greater energy efficiency by reducing heat loss. In addition to draught reduction, some automatic drop-down seals can also assist with acoustic performance and smoke containment when used as part of a tested door sealing system.
