Vector Foiltec Texlon ETFE Architecture and Engineering Solutions
What is Vector Foiltec Texlon ETFE and how is it used in advanced building projects?
Vector Foiltec Texlon ETFE is an architectural ETFE foil system used for lightweight, transparent building envelopes and complex roof structures. The technology combines pneumatic foil cushions, precise engineering and digital planning methods to create large-scale structures with low material weight. More information about ETFE systems can be found at Vector Foiltec.
The Sport- & Wellnessbad architecture project demonstrates how ETFE-based solutions can be combined with advanced standing seam technology, BIM coordination and detailed structural planning. The project required extensive preparation during the design and tender phases, including feasibility studies, 3D modeling and coordination between architectural, structural and production teams.
Vector Foiltec Texlon ETFE planning: How does digital engineering support complex structures?
ETFE foil architecture, Texlon systems and lightweight building envelopes
The use of Vector Foiltec Texlon ETFE requires accurate digital models and detailed coordination. For the Sport- & Wellnessbad project, the engineering process included:
- Feasibility studies during design and tender phases
- 3D modeling of standing seam surfaces and profile distribution
- Surface optimization based on initial scan data
- Adjustments according to PV panel layouts
- Allocation of standing seam panels to final surface geometries
- Coordination of connection heights and boundaries
How are ETFE structures prepared for BIM integration?
Vector Foiltec Texlon ETFE models for construction planning
The project models were prepared for integration into the building’s BIM process. Installation models and overview drawings supported coordination between different project participants and construction phases.
The work included coordination with the local structural engineering office, preliminary substructure design based on structural calculations, and finalization of substructures using detailed area scans.
Vector Foiltec Texlon ETFE and BEMO standing seam systems: How are components coordinated?
Lightweight roof systems, ETFE envelopes and standing seam integration
The Sport- & Wellnessbad project combined digital scan technology with large-scale standing seam surfaces. The planned products included:
- BEMO Standing Seam 65-400 / 1.00 mm (88,200 m²)
- BEMO FLEX Substructure (approx. 82 km of individual custom elements)
- Production data for approximately 510,000 FLEX elements
- Gutters including flexible substructures
- Ridge and special extrusions
- BEMO Accord Rail (approx. 10 km)
Further information about BEMO standing seam systems is available at BEMO Systems GmbH.
Vector Foiltec Texlon ETFE project challenges: What required special engineering attention?
ETFE foil structures, scan-based planning and complex construction phases
The Sport- & Wellnessbad architecture required coordination across multiple disciplines and locations. Major challenges included:
- Very tight schedules for individual construction sections
- Four separate buildings
- BEMO FLEX substructures based on scan data
- Deflection of the primary structure
- Sequential construction planning
- Coordination across multiple time zones
- Alignment with PV panel layouts and connection details
How were scan data and production details managed?
Vector Foiltec Texlon ETFE digital workflows for accurate fabrication
Around 360 individual scans were required to finalize approximately 130 areas and sections. Scan data helped adjust gutters, connection details and substructures before manufacturing. This reduced uncertainty during installation and supported precise fabrication processes.
Technical background about ETFE applications is also available through the Fraunhofer Institute for Building Physics and the European Aluminium Association.
