Objetivo INFRARED REFLECTIVE COATING ON GLASS PANES KEEPS HEAT RADIATION IN THE HOUSE AND THUS CONTRIBUTES TO ENERGY SAVING. HOWEVER, WINDOW COATING CAN ONLY TAKE PLACE IN THE FACTORY. THIS IS EXPENSIVE AND IN ORDER TO AVOID THIS PROBLEM IT WAS DECIDED TO DEVELOP COATED PLASTIC SHEETS WHICH CAN BE EASILY FIXED ON WINDOWS. R AND D BY THE UNIVERSITY OF LOUGHBOROUGH, UK RESULTED IN A TECHNIQUE COATING PLASTIC SHEETS. A PROBLEM WAS THE LOW TRANSPARENCY FOR VISIBLE LIGHT WHICH WAS ONLY 60 % FOR TIO2/AG/TIO2 COATINGS BUT WHICH WAS IMPROVED TO 75 % USING MIXTURES OF CADMIUM AND INDIUM OXYDES. IT WAS ALSO FOUND THAT SINGLE WINDOWS, WITH A COATED PLASTIC SHEET, REFLECT THE HEAT RADIATION SO WELL THAT THEY REMAIN COLD AND ARE COVERED WITH CONDENSATION WATER WHICH IS OPAQUE FOR HEAT RADIATION AND SPOILS THE EFFECT OF THE HEAT REFLECTIVE LAYER. COATED PLASTIC SHEETS ARE THEREFORE NOT VERY EFFICIENT HEAT MIRRORS WHEN THEY ARE FIXED ON SINGLE WINDOWS. THEY MAY HOWEVER BE USED AS SECOND WINDOWS. A COMBINATION OF A GLASS-PANE WITH A COATED PLATIC SHEET AT A DISTANCE OF 20 MM HAS A HEAT TRANSMISSION COEFFICIENT OF 2 W/M2 DEGREE K (SINGLE GLASS WINDOWS HAVE 5-6 W/M2 DEGREE K). SUCH A WINDOW HAS THE ADVANTAGE OF BEING LIGHT AND CHEAP. (THE COST OF COATED PLASTIC IS 1 - 1,5 ECU/M2 AND PAYBACK TIMES ARE EXPECTED TO BE SHORTER THAN ONE YEAR). AS THE COATING IS RESISTENT AGAINST SCRATCHING IT MAY ALSO BE USED ON ROLLING BLINDS. THIS PROJECT HAS A FOLLOW-UP IN A CEC DEMONSTRATION PROJECT WHERE THE ECONOMIC FEASIBILITY WILL BE DEMONSTRATED.
