The lattice shell is considered to be one of the most efficient surface structures which is able to span unsupported over wide spaces with minimal material input by using a net of bar-shaped elements. The special thing about "Plusminus" the pneumatic lattice shell is the minimal dead load of the structure. The bar-shaped elements are connected flexible at their cross-over points and shape a grid shell. "Plusminus" attains the fixing of the cross-over points and thereby the bracing of the framework by evacuating two foil coverings which are situated above and under the grid and are pressing the cross-over points together.
