A glass laminate for greenhouse, comprising a heat ray-reflecting film laminated on one side of a transparent glass, which glass laminate is characterized in that(1) the heat ray-reflecting film comprises a transparent thermoplastic resin film and at least one metal oxide layer and at least one metal layer, both formed on one side of the resin film,(2) the glass laminate has the heat ray-reflecting film laminated, via an adhesive layer, on one side of the transparent glass, at the side opposite to the thermoplastic resin film side,(3) the glass laminate has a film for prevention of growth of the waterdrops formed by dew condensation, which is formed on the surface of the thermoplastic resin film, and(4) the glass laminate has an integral transmittance of 55% or more for a visible light having a wavelength of 400 nm to less than 750 nm and an integral transmittance of 50% or less for a near-infrared light having a wavelength of 750 nm to less than 2,100 nm; and a greenhouse wherein the above glass laminate is used at the lighting area so that the glass surface is positioned outside the greenhouse.The glass laminate for greenhouse of the present invention has excellent transmission for visible light and is superior in prevention of daytime temperature increase inside greenhouse, prevention of nocturnal radiational cooling and prevention of falling of the waterdrops formed by dew condensation. |
