PROBLEM TO BE SOLVED: To provide a glass laminate composed of different thickness glasses that can improve the acoustic insulation as well as that can contribute to bringing the transmittance of infrared-ray within a given range.SOLUTION: A glass laminate includes: an outside glass plate 1; an inside glass plate 2 disposed oppositely to the outside glass plate and having a thickness smaller than that of the outside glass plate; and an interlayer 3 held between the outside glass plate and the inside glass plate. In the glass laminate, a transmittance of light having a wave length of 850 to 950 nm is 30 to 80%, the thickness of the outside glass plate is 1.8 to 2.3 mm, the thickness of the inside glass plate is 0.6 to 2.0 mm, the interlayer is composed of a plurality of layers at least including a core layer 31, and a Young's modulus of the core layer at a frequency of 100 Hz and at a temperature of 20°C is 1 to 20 MPa and is lower than a Young's modulus of the other of the aforementioned layers.

    【課題】遮音性を向上できるとともに、赤外線の透過率を所定範囲にすることが寄与できる、異なる厚みのガラスで構成された合せガラスを提供する。【解決手段】合わせガラスは、外側ガラス板1と、前記外側ガラス板と対向配置され、前記外側ガラス板よりも厚みが小さい内側ガラス板2と、前記外側ガラス板及び内側ガラス板の間に挟持された中間膜3と、を備え、波長が850〜950nmの光の透過率が30〜80%であり、前記外側ガラス板の厚みが1.8〜2.3mmであり、前記内側ガラス板の厚みが0.6〜2.0mmであり、前記中間膜は、少なくともコア層31を含む複数の層で構成されており、前記コア層のヤング率は、周波数100Hz,温度20℃において、1〜20MPaであり、他の前記層のヤング率よりも低い。【選択図】図1
