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 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 room doors and front doors. Our automatic door seals are also used in radiation protection doors and double-wing door systems.

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.
