Installing an automatic drop seal is always a good idea, because it noticeably increases living comfort. Its use offers reliable protection against noise and sounds, dust, dirt and unpleasant draughts. And it works like this: when the door is closed, the seal lowers automatically due to a release mechanism. The bottom gap between the floor and the door closes and noise, draughts and cold no longer have a chance to enter the room.

Our range of perimeter seals has been curated to offer solutions for a wide range of gap sizes, fixing locations and applications. This includes rebated, self-adhesive and surface-mounted options for both door stops and frame reveals. Some seals act as compression seals, shaped so that they compress against the door when it is closed. Others perform as a sweep seal, sweeping against the door edge as the door moves into a closed position.

Our range of aluminium and stainless steel threshold plates provide a stylish connection between two rooms or spaces, covering the gap between different floor types and thicknesses. The range can be supplied with or without pre-drilled holes, providing the option for a more practical, screwed installation or a more aesthetic, screw-free installation with adhesive.

athmer has been involved in the manufacture of automatic drop seals for over 60 years. The combination of experience, competence and quality enables permanent further development of the product range.
With the most extensive range on the market, athmer covers almost every application.

athmer fiinger protection systems have been proving their worth on doors for 30 years and prevent injuries by reliably avoiding the risk of fingers being accidentally trapped on the closing edges. Finger protection roller blinds, pinch guards and protective profiles on the hinge side significantly reduce the risk of injury in kindergartens, hospitals and clinics as well as other public facilities.

For interior doors, the perimeter seal serves as a damping profile that allows the door to close quietly. Exterior doors receive reliable protection against moisture, noise and insects. Functional doors benefit from professional sound and smoke protection.

The Porti^® eliminates the need for door stops on the floor, thus avoiding tripping and bumping points and facilitating cleaning in this area. The Porti^® is therefore ideal for rooms with underfloor heating. This makes the Porti a safe, accident-free solution with high demands on design, hygiene and accessibility. It is particularly suitable for use in hotels, public facilities, banks and doctors' surgeries.
