Roof covers serve to define the upper part of a building and to protect the indoor environment from atmospheric agents. The main aim of roof covers is to prevent moisture from arising, to withstand any load, including wind and snow loads, and to minimise the loss of heat out of the building. A cover seal, i.e. the outer layer of roof covers, ensure watertight while the skeleton serves to support the seal itself.
There are available on the market several systems for manufacturing precast roof covers and that are of particular importance especially in case of industrial and commercial buildings. The latest systems in the art provide the use of prestressed wing-shaped roofing beams, usually mounted at 5 m intervals and in combination with curved or plane plate. These systems ensure a high functional and aesthetic performance with wide structural framework, reduced weight, wastewater disposal, elegant shapes and natural lighting customisable at your convenience.
