Athmer Schall-Ex® L-15/30 WS Drop Seal

The Athmer Schall-Ex® series is a high-performance sealing system that automatically closes the gaps under the door to prevent the passage of sound, dust, odors, and drafts. When the door closes, the seal descends parallel to the floor thanks to its spring mechanism, operating silently and preventing floor scratches.

It provides sound insulation up to 52 dB and contributes to energy savings. Its actuator is designed to be adjustable without tools and protected during construction; offering a combination of aesthetic and technical harmony.
