Provided is a dimmable window equipped with a dimmable sheet material having an improved anti-glare feature and improved resistance to external force. In the dimmable window 10 according to the present invention, the dimmable sheet material 14 is enclosed in a hollow layer 24 in a multi-layered glass 12 comprising an outdoor-side glass sheet 16 and an indoor-side glass sheet 18. One of the outdoor-side glass sheet 16 or the indoor-side glass sheet 18 has a visible light transmittance of 70% or less. If the one of the glass sheets is the outdoor-side glass sheet 16, the transmission amount of external light reaching the dimmable sheet material 14 can be reduced, so that glare occurring when the external light is diffused by the dimmable sheet material 14 can be reduced. Alternatively, if the one of the glass sheets is the indoor-side glass sheet 18, glare occurring when the external light is diffused by the dimmable sheet material 14 can be reduced by the indoor-side glass sheet 18. Moreover, the dimmable sheet material 14 is protected by the multi-layered glass 12, so that the resistance to external force is improved. |
