Why Athmer Door Seals?

Simply put, they offer the best product. No more spring failures, scratched floors, weak springs or installation problems. Athmer has worked out all the common complaints with existing drop down seals. And to protect the seals during the construction phase (so they are not deployed on rough floors with construction debris), you can REMOVE the deployment mechanism so they are not activated until the floor is installed and/or cleaned!

Our Mini Review

Athmer seals are cycle tested to 1,000,000+ cycles. They simply won't fail. We constantly hear reviews of other drop seals that only last several months before the spring mechanism fails. Not with Athmer seals -- simply the best seal on the planet.

Need a quite office space? HIPPA privacy space? Odor containing space-- keep it in. Private doctor office? Any space requiring privacy, draft protection, air/odor isolation can be enhanced by an Athmer drop door seal.  Also checkout zero threshold solutions or rain penetration solutions on our sister site:

Installation Instructional Video

Some competitors offer up to 12" of cut back in the field so their standard lengths will fit many different door widths. This high cut back length simply leads to weak spring strength towards the lock side. Athmer has fine-tuned its standard lengths to ensure a reasonable cut back length while ensuring equal spring strength across the entire length of the drop seal. No spring failures and a perfect seal.

Loose the threshold! NO MORE TRIPPING HAZARDS!

With Athmer drop seals, tripping hazards on door thresholds are a thing of the past. All athmer sealing systems are barrier-free - with no ifs or butts. Our zero threshold solutions for doors even fall below the requirements of the German Industrial Standard (DIN 18040). This standard tolerates threshold heights of up to two centimeters, even for barrier-free construction.

Barrier Free Entry

At athmer, the motto is: "Zero means zero". - And that with increased tightness. Our systems Schall-Ex®, Stadi-L, Doppeldicht® and Kältefeind®, are certified according to the standards for barrier-free planning, building and living (DIN 18040) and meet the requirements for the permissible operating forces for barrier-free doors according to DIN EN 12217. The specially developed release mechanisms of the athmer drop seals mean a plus in independence and freedom of movement, especially for people with restricted mobility, especially for wheelchair users For athmer, the optimal ease of use of doors has traditionally been at the top of the product development agenda. Today we see that the requirements for barrier-free planning and construction are becoming more and more important. With athmer sealing systems, door manufacturers and builders are on the safe side when it comes to accessibility. This applies to our standard systems as well as to individual solutions that we develop together with our customers.
