Optically clear polyester insulating window films, (that are UV-stabilized, hard-coated, and encapsulate sputter/vapour-depositions of any number of metals and oxides, or IR-blocking nano-particle dispersions) are making it painless to upgrade the solar performance of standard glazing systems. These performance films offer overall energy savings for qualified buildings of 5-10 per cent, and common payback periods of 1-4 years.
