1. Material Composition:
- Housing: Made from high-quality aluminum alloy, known for its durability, corrosion resistance, and lightweight properties.
- Seal Insert: Equipped with a flexible rubber or silicone gasket (e.g., EPDM, neoprene, or silicone), which conforms to floor surfaces to block air, sound, dust, smoke, and insects.
2. Soundproofing Functionality:
- Designed to significantly reduce sound transmission through door gaps (typically rated at 30–50 dB sound attenuation, depending on installation and seal type).
- Helps maintain acoustical integrity in spaces like recording studios, conference rooms, hotels, offices, or medical facilities.
3. Automatic Drop Mechanism:
- Features an internal spring-loaded or gravity-activated mechanism that automatically lowers the seal when the door is closed, creating a tight seal against the floor or threshold.
- Retracts when the door opens to prevent drag or damage.
4. Installation:
- Can be surface-mounted or mortised into the bottom edge of the door, depending on the model and door design.
- Lengths are often adjustable or available in custom sizes for precise fitting.
5. Advantages:
- Improved acoustic isolation
- Energy efficiency by preventing air leaks
- Protection against dust, insects, and light
- Durable and long-lasting design due to aluminum housing
