The main concept of this project is usage of air entrapped in a closed volume of exterior walls of a structure as an thermal insulation. Final outcome of this project is a product of designing a structure which inherit all positive factors of inflatable structure (fast assembly, good thermal insulation, easy transportation) and lacks its disadvantages (it does not affected by punctures and other physical damage). Two major building materials used in this shelter are plastic panels and moisture resistant fabric. Thin plastic panel with larger radius is bended and fixed with a fabric of smaller radius. This produces building blocks from which shelter is assembled, gaining an effect of inflatable capsule. In fist conceptual design this panels were put on a plastic framework in a rectangular structure in order to acquire structural stability. But after some considerations observation was made that panels themselves have a structural stability in vertical direction because of their unique geometric shape. Using CAD program sophisticated shapes for plastic panels were designed in order to assemble a dome-like structure from bent plastic panels which could support itself and also withstand horizontal and vertical forces of elements (snow, wind, etc.) Plastic panels also provide good protection from physical penetration of hail and other natural and artificial hazards. This design require very careful and exact prefabrication of major components. How ever the construction of this shelter on site will need minimal knowledge, experience or time. Especially if fabric portion of building blocks is prefabricated into a tent-like structure. In this case plastic panels could be bent and directly apply on the tent using special prefabricated tent pockets. Because of specific design this shelter does not require large amounts of materials in order to sustain structural and thermal integrity. All materials could be packaged into relatively small container.
