Resumen
The invention constitutes a new solution for a vertical joint for systems of prefabricated parts for straight fabric facades characterised by the inclusion of a double-sealed joint part. The objectives of the invention include the configuration, the design of the joint part and the side ends of the surface parts and the process of application. The new configuration facilitates manufacture of the parts forming a prefabricated system for a facade, reduces the effect of climatic action on the joint material, improves the behaviour of the material and permits a wide variety of compositions of the facade.
