POLITECNICO of Milano and POLITEC of Sondrio organized this special event on the 26th October 2016. During the meeting we gave information to partecipants about TILLICA product that can be used in the construction world. TILLICA is an innovative system made with lime putty and aerogel nanotechnology patented and certified, reflecting, thermal insulating, eco-sustainable, fire-resistant class A1. TILLICA combined with heat pump, brand DAIKIN, in residential and commercial buildings is the best technology solution with high energy efficiency. Thermal insulation is very important to define the energy efficiency of a building, that means it’s necessary to choose the power of the generator, warm or cold way, and define the real energy efficiency. The meeting organized by companies who are leaders in each working sector was very appreciated: the partecipants were very interested in and very interested in innovative technology and the respect of the environment.
