An inflatable structure may seem simple when it is assembled. Before reaching that point, the material will have gone through cutting, joining of pieces, transport, folding and numerous installation cycles. Each stage influences fabric selection. A solution that works when spread out may be awkward to handle if it takes up too much volume when stored.
Terraza works with lightweight, high-tenacity fabrics for inflatable and aerostatic applications. In this type of project, it is advisable to define from the outset the function of each component: the structural shape, the air barrier, the reinforcements and the joining elements do not always lie within a single layer.
Study the use before designing the sample
Will the structure remain assembled for several days, or will it be installed and dismantled frequently? Will it be transported in a small vehicle? Will there be areas that rub against the ground or anchor points subject to repeated stresses? These questions help prioritise weight, flexibility and protection of critical areas without adding material where it is not needed.
The environment also matters. Exposure to sunlight, humidity, dirt and the intended cleaning method must be described precisely. For a temporary outdoor application, actual installation conditions are usually more relevant than a generic “outdoor use” label.
The joint can determine the result
A structure consists of panels, seams or welded joints, valves and reinforcements. The compatibility of the fabric with the intended joining method must be checked using fabrication samples. The airtightness of the system cannot be inferred solely from the surface of the material: it also depends on how intersections and specific points are resolved.
In complex prototypes, it is useful to identify from the outset the areas that require a different construction. A localised reinforcement can protect an anchor point without turning the entire structure into a heavy or difficult-to-fold element.
Test the complete cycle
Assembling, using, deflating, folding and reassembling is a more informative test sequence than observing a newly manufactured piece. It makes it possible to detect fold marks, handling difficulties and fabrication decisions that should be reviewed. Safety or fire performance requirements, where applicable, must be specified and verified for the application and the final product by those responsible for the project.
Sharing drawings, dimensions, joining method and frequency of use makes it easier for the manufacturer to guide development. The right fabric is an important part of the solution, but it always works within a system.
