ATHMER range of products

Athmer has the right product for practically every type of application

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 wooden doors

Our sealing systems for wooden doors are extremely versatile. We fit them in smoke, fire and acoustic doors as well as in damp and wet rooms and front doors. Our automatic door seals are also used in radiation protection doors and double-wing door systems.

We have now set new standards with our successfully passed endurance tests: Our sealing systems passed one million testing cycles with flying colours. For our customers, this means: Athmer systems are a safe long-term, sustainable investment. They conserve resources and ensure that buildings have an optimised eco-balance.

Environmental Product Declarations (EPD) are available for our automatic door seals. 

Data basis for building certification in compliance with European standard 14025 and national standards such as DGNB (D), BREEAN (UK), LEED (USA), HQE (F), CASBEE (JPN).

Seals for system doors

Made-to-measure doors for systems call for customised sealing solutions. Doors for use in systems are typically installed in public buildings, factory halls and other industrial buildings.

When it comes to sealing, the customer’s specific requirements are particularly important.

Athmer door seals are ideal for all types of system doors: Indoor and outdoor use, single-wing or double-wing door systems, smoke, fire and acoustic doors.  

Automatic height and level adjustment offers added flexibility and safety: the seals are self-adjusting if the conditions change. Furthermore, the sealing systems include integrated overload protection as standard.

Glass door seals

Athmer sealing systems for all-glass doors are versatile in use and provide a reliable seal - whether for standard doors or commercial doors. Our sealing systems are ideal both for hinged doors and sliding doors (including automatic sliding doors), no matter how thick the glass is.

All automatic door seals for glass doors are supplied with the U-sign of compliance. We have now set new standards with our successfully passed endurance tests: Our sealing systems passed one million testing cycles with flying colours.  

With their verifiable high-quality performance, Athmer systems are a safe long-term, sustainable investment for our customers. They conserve resources and ensure that buildings have an optimised eco-balance. 

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 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 sealing systems for gates and doors are fitted with automatic height and level adjustment and can easily cope with the special requirements of doors and gates incorporating a wicket door. A multi-part sealing concept with continuous actuation is used here.  

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.  

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.
