Automatic door thresholds

Automatic Drop Seals – Tight Seal and Comfort

Automatic door drop seals provide effective protection against drafts, dust, moisture, and noise. When the door closes, the seal automatically drops and tightly presses against the floor, creating a secure barrier. This is especially important in rooms where sound and thermal insulation matter.

Benefits of automatic door seals:

• Improved sound and thermal insulation
• Protection from drafts and insects
• Discreet appearance – invisible when the door is open
• No electricity required – fully mechanical operation
• Compatible with hidden, interior, and fire-rated doors

The seal is installed inside the bottom of the door leaf and activates automatically when the door closes. Suitable for residential and commercial spaces where comfort and energy efficiency are priorities.
