PURPOSE:To manufacture composite-layer glass having the function for preventing dew condensation by constituting an electrically-conductive layer formed with a metallic layer on a transparent resin film between two sheets of glass plates and interposing both a heat-ray reflective film layer for conducting electricity to the electrically- conductive layer and a space layer having proper thickness via a spacer to the parallel end parts thereof. CONSTITUTION:An electrically-conductive layer wherein a layer of metal (silver, gold and copper or the like) and/or metallic oxide (SnO2 and In2O3 or the like) having <=5,000Angstrom preferably 50-1,000Angstrom thickness is formed on a transparent resin film (polyethylene terephthalate or the like and about 25-100mu thickness) is constituted between two sheets of glass plates. The resin film constituting this electrically-conductive layer has about 80% visible light transmission and about 90% infrared reflection coefficient. Further both a heat-ray reflective film layer for constituting an electrode and a terminal conducting electricity and a space layer are interposed to the parallel end parts of the electrically-conductive layer by utilizing a spacer. Thereby a composite-layer glass which is available and transparent and has the function for shielding heat rays and the function for preventing dew condensation is obtained. |
