Abstract:
There is provided laminated glass with a heat shielding property in which a need to change an intermediate film is reduced even though thicknesses of glass plates are changed. Laminated glass of an embodiment includes: a pair of glass plates; and an intermediate film sandwiched between this pair of glass plates. A total thickness of the pair of glass plates and the intermediate film is 3.6 mm or less. Further, a ratio (A2/A1) of an absorbance (A2) of the intermediate film at the wavelength of 1500 nm to an absorbance (A1) of the pair of glass plates at a wavelength of 1500 nm is 2.0 or more when plate thicknesses of the pair of glass plates are each set to 2.0 mm. Further, a solar radiation transmittance (Tts) provided by ISO13837 (2008) is 60% or less.
