The new Stadi

The classic for system doors

Whatever demands are placed on a seal: The Stadi meets them. The new version of Athmer's Stadi sealing range for system doors made of plastic, steel or aluminium is so versatile and adaptable that it covers a wide range of applications. All Stadi versions are based on the same mechanical philosophy and this brings many advantages with it – such as parallel lowering, the lack of an inner rail offset or the option of time-delayed closing.  


the synonym for autom. drop seals

The youngest generation of the Schall-Ex® L-15 sets new standards in the market. The solutions of the product range have excellent sound insulation values, a sturdy mechanism and are very easy and quick to mount.

Athmer Rainstop®

Zero means zero - seals for exterior doors

The Athmer Rainstop® stands for certified quality: the renowned ift Rosenheim certifies the new sealing system's resistance to driving rain, resistance to wind load and excellent sound reduction values. The Athmer Rainstop ®for barrier-free exterior doors is used in many places such as private homes, retirement homes, hospitals, hotels and public buildings  


sealing system for retrofitting

The new NADI® sealing system for retrofitting improves sound absorption values and updates existing fire doors to smoke doors. As the first and as yet only system on the market, NADI® has a flexible and resiliently mounted sealing profile which effectively balances out and withstands heat deformation of the door leaf > 10 mm, and optionally even > 14 mm.


Zero means zero!

Athmer door seals make trip hazards at door thresholds a thing of the past. All Athmer sealing systems are barrier-free - without any ifs and buts. Our zero threshold solutions for doors even meet the requirements of the German industrial standard (DIN 18040). This also tolerates threshold heights > two centimetres for barrier-free construction. But at Athmer, we go by the maxim: Zero means zero!” - and this goes hand in hand with enhanced sealing properties.

Our systems Schall-Ex®, Stadi-L, Doppeldicht® and Kältefeind® are certified in accordance with the standards for barrier-free planning, construction and living (DIN 18040) and meet the requirements for permitted operating forces for barrier-free doors in accordance with DIN EN 12217. The specially developed actuation mechanisms for Athmer door seals mean more independence and freedom of movement, particularly for people with reduced mobility, especially for wheelchair users.

For Athmer, the optimum operating comfort of doors has traditionally been at the top of the agenda in product development. Today, we are experiencing that the requirements for barrier-free planning and construction are becoming increasingly important. With Athmer sealing systems, door manufacturers and building owners are on the safe side when it comes to barrier-free access. This applies to our standard systems as well as to individual solutions that we develop together with our customers.
