The paper presents the experimental results on depositing a multilayer low-emissivity (low-E) coating with oxide-metal-oxide structure on polyethylene terephthalate (PET) and polyethylene (PE) films by magnetron sputtering. The TiO2/ZnO:Ga/Ag/ZnO:Ga/TiO2 coating on the PET film with high water-resistance and capability to be used outside of sealed double-glazed panes was proposed. The optimal thickness of coating layers was experimentally determined. The coating with the optimal structure has 82% transmittance over the visible spectrum and 91% reflection over the infrared spectrum. The window with a PET film and low-E coating was investigated in terms of heat engineering. It was revealed that heat transfer resistance increased up to 0.73 m(2) C W-1 for the windows with a PET film and low-E coating. Heat transfer resistance of the windows without a polymer film was 0.38 m(2) degrees C W-1. The water-resistant ZnO:Ga/Ag/ZnO:Ga/SiO2 coating on a PE film with 77% transmittance and 91-92% reflection in the IR range was proposed to be used as greenhouse covering material. The possibility of using the PE film with a low-E coating to reduce heat loss in greenhouses and enhance yielding capacity was demonstrated. (C) 2015 Elsevier Ltd. All rights reserved.
