The classic drop seal

Consistently positive feedback and enthusiastic customers confirm the exceptionally high sound insulation values of the seals. With a 7 mm gap (between floor and door), the Schall-Ex® L-15 now achieves values of 52 dB, with a 15 mm gap it is still 51 dB, with which athmer has set a new industry-wide benchmark with the proven groove dimensions of 15 x 30 mm.

Even in double-leaf door systems with the optimally matched flush bolt - which athmer supplies directly if required - the Schall-Ex® provides excellent sealing, as the projection of the sealing profile on the closing sides of the door leaves no gap.

Mit Türkantriegel und Treibriegel bietet athmer zwei funktional unterschiedliche Verriegelungslösungen für die Schall‑Ex® und Stadi Modelle an.
