The new Stadi family

The classic for systems and metal 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 Athmer Rainstop ®for barrier-free exterior doors is used in many places such as private homes, retirement homes, hospitals, hotels and public buildings  



Retrofitted sealing system

NADI® optimises the acoustic and smoke protection values of existing doors reliably and to DIN-certified standards. NADI® is suitable for fire dampers, sound-, smoke-, moisture-proof and air-conditioning doors made of metal, wood, glass or plastic as well as for barrier-free doors.    



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.

Seals for sliding doors

Athmer sealing systems can easily handle the complex requirements associated with sliding doors. They are suitable for all materials: wood, metal, plastics and glass.

They provide superior sealing for door systems with and without locks as well as for automatic sliding doors – especially in combination with Athmer thresholds. They also comply with the requirements for barrier-free buildings.

Athmer sliding door seals rely on proven technology: our Doppeldicht®, Schall-­Ex® or Stadi systems are used, depending on the groove width. All sealing systems on the basis of Schall-Ex® Ultra have integrated overload protection as standard (optimised contact pressure with floor)  and higher safety of use through self-adjustment to floor conditions. 

All sealing systems for sliding doors can also be retrofitted.

Seals for retrofitting

Many Athmer door seals can easily be retrofitted - with little installation work during day-to-day use. Our retrofit seals are suitable for various materials (wood or glass) and different types of doors (sliding or hinged, single or double-wing doors).

Retrofits optimise fire and smoke control, improve acoustic and draught tightness and solve problems posed by warped doors or uneven floors.

Retrofitting sealing systems helps to save heating costs, enhances living comfort and well-being and improves the energy balance of the building.

Seals for gates

A particular speciality at Athmer are their sturdy sealing systems for gates and doors. They are ideal for wooden or steel hinged or sliding doors and gates, even if they have extremely wide gaps.

The gate or door seals comply with all smoke and fire regulations. They have a sound reduction of > 50 dB.  

The Athmer range for gates and doors also includes brush seals - a trouble-free and affordable seal to keep out draughts, the cold, dampness, leaves or vermin. The form and material used vary depending on the installation situation and the degree of corrosion resistance required.
