TENTAL is TECHNAL’s new aluminium façade. It has been designed with the aim of offering architects and consultants a wide range of solutions, giving them the greatest possible creative freedom, and developed for large glazed window spaces and with the lowest environmental impact. Four new patents, related to the ease of assembly, which enable optimisation of the materials, simplifying manufacturing and facilitating the installation that is done dry, without glue, without sealants and without waste, seeking the maximum feeling of transparency and the minimum visualisation of the profiles.
