Texlon® cushions can be manufactured in large sizes and can span much greater distances than conventional cladding technology. This provides designers with the opportunity to integrate the design of the cladding with the primary structure, developing simplistic and rational aesthetics.
The technology is ideal for use where bomb blast or hurricane loadings need to be incorporated into the design. The material's innate toughness and high resistance to tearing within the 300-400% elongation range, means that Texlon® can naturally deal with very large deflections in the support structure.
As the Texlon® cushions are large and pneumatically pressurised, the air acts as a fluid, damping short term loads, reducing their intensity, and decreasing the overall loads imposed on the primary structure. This has enabled the development of ultra lightweight structures such as uni-axial cable nets and large scale geodesics.
All load cases need to be considered, including potential water ponding loads for cushions at horizontal, or near horizontal, orientation. The membrane stresses generated by inflation and external loads define the overall geometry of the form, the maximum span, the radii of curvature and the thickness of the foils making up the cushion.
The engineering of Texlon® is a very specialist area as the material's qualities and performance make it unique. Vector Foiltec provide a full engineering and patterning service, including proprietary non-linear load analysis and patterning software. In addition, we frequently design, engineer and erect the entire envelope including all support structures, opening panels for ventilation and adjacent cladding.
We recommend an early consultation with our engineers in the development of design proposals in order to take full advantage of the opportunities offered by Texlon®'s unique properties, and allow early definition of an economic structural grid and design concept.
