Keder profiles for ETFE – level connection


Double keder profile for flat substructure


3dtex GmbH has developed a new product that combines a variety of functions in a compact design. It is equipped with an internal condensation channel that also acts as a secondary sealing level. The profile system has a thermal separation. This reduces thermal losses in heated buildings.
The base profile is screwed directly to the substructure using self-drilling and self-tapping screws. The result is an aesthetically pleasing, compact design that differs significantly from the usual construction with individual brackets. The system allows even complex geometries to be reliably sealed against heavy rainfall.
Installation is quick and easy. Sophisticated installation tools can be provided.

Double keder profile for connection bracket


This double keder profile for ETFE foil roofs is a new development of 3dtex GmbH which integrates a wide range of functions in a compact design. It has an internal condensation channel, which also functions as a second sealing level. This means that even complex geometries can be reliably sealed against driving rain.
The profile system has a thermal separation to reduce losses in heated buildings. It allows the creation of spatially complex corner geometries and their secure sealing. Installation is quick and easy. Sophisticated installation tools can be provided.
DK-06-SSL-BPB
- for 6mm keder
- attachment to brackets of the substructure using M8 hammerhead bolts in a channel – no complicated threading necessary
- base, middle, keder and cover profile made of anodized aluminium 6063 T66
- incl. protective and sealing profile made of UV-resistant EPDM 70 Shore A
- incl. second sealing level to absorb possible condensation or minor leaks, made of self-adhesive laminated EPDM, easy and safe to install even in complex corners
- complex node geometries can be realised
- incl. thermal break with polycarbonate spacer sleeves
- incl. connecting pins for precise alignment of the profiles
- incl. optional bird defence system
Double keder profile DK-06-BPB


This standard double keder profile enables the formation of a tight water channel between two ETFE cushions and is therefore suitable for façade and roof constructions.
- for 6mm keder
- attachment to brackets of the substructure using M8 hex head bolt
- base, keder and cover profile made of anodised aluminium 6063 T66
- incl. protective and sealing profile made of UV-resistant silicone 70 Shore A
- incl. connecting pins for precise alignment of the profiles
- optional secondary sealing level / condensate channel
- optional bird defence system
