A large number of materials has been subjected to theoretical and experimental investigation. The application of TIM range from windows, industrial glazings, high temperature collectors, integrated storage collectors and seasonal storage to transparently insulated buildings.enheat loss coefficienthouse heatingintegrated storage collectorslong-term storageprocess heattransmittancetransparent insulation material621697conference paper
