Sealing system

The NASSAU 9000 range is fitted with an effective system of seals against wind and rain. 

The top section is fitted with a seal that runs along the horizontal frame attached to the building made of TPE – a plastic with exceptionally good shape-retaining properties. The same material is also used for the integrated seals between the door sections.The bottom section has a specially-developed rubber profile with no less than 3 separate seals, made from EPDM which also has extremely good shape-retaining properties.

Furthermore, the NASSAU 9000 has a set of seals fitted to the vertical door rails, to provide an efficient seal between door leaf and building.
