As a company with ISO 9001 accreditation, the quality of all processes, procedures and products is crucial for seele. Lightweight membrane designs in the form of transparent, coloured or printed ETFE film cushions or membrane shade sails in double curvature are designed and fabricated by seele with the utmost quality and precision and, depending on requirements, with or without a load-bearing structure.
It is precisely the fabrication of and connections between ETFE film that call for a wealth of experience when forming plate and shell structures in double curvature. Factors such as temperature and time influence the behaviour of the material. Form-finding, stress calculations, generating cutting patterns and fabricating surfaces in double curvature, also for oversize formats and spans, are all complex issues. All the relevant know-how is available at seele: high precision in the planning process, taking into account the structural and constructional influences and requirements specific to each material.
seele exploits the options for ETFE
Outstanding ETFE expertise is one of seele’s strengths. Welding machines optimised by seele engineers produce weld seams in excellent quality which are tested in seele’s own test centre. Those ETFE skills are brought together by seele in an engineering department staffed by highly qualified architects, engineers, technicians and designers. The proven, acknowledged safety concept for the use of ETFE film as structural components in architecture and construction, which was developed by seele, forms the basis for all calculations.
Cooperations and interdisciplinary research projects with universities and research bodies, e.g. the DFG, Technische Universität München, Anhalt University of Applied Sciences, the Fraunhofer institutes, enable seele to generate new impulses in research as well.
