    Athmer Schall-Ex®

    The classic seal

    Positive feedback throughout and enthusiastic customers confirm the exceptionally high sound reduction values of the seals. With a sealing height of 7 mm, the Schall-Ex® L-15 now reaches values of 52 dB, and with a 15 mm sealing height it is still 51 dB, which means that Athmer has set a new industry-wide benchmark with proven groove dimensions of 15 x 30 mm. Even with double-leaf door systems with the optimally matched flush bolt - which Athmer supplies directly as required - the Schall-Ex® provides excellent sealing performance, since the protrusion of the sealing profile on the closing side of the door leaf eliminates any gaps.

    The new generation of automatic door seals

    Tool-free adjustable sliding actuator saves time

    The new generation of seals can also be installed much faster and thus more cost-effectively. Thanks to a standard and tool-free adjustable sliding actuator, there is no need to invest time in attaching a protective pressure plate - even with varnished wooden frames. This is an enormous advantage, both functionally and visually! The clip-on actuator, which can also be retrofitted, also has another tangible advantage: This means that the seal can be actuated and put into operation for the first time when the new building is ready for occupancy. This ensures that dirt, debris and dust from the construction site do not damage the sealing profile in advance or impair its function.
