Abstract
A laminated pane for a window includes (1) a first sheet having a first thickness and a first coefficient of thermal expansion (CTE), (2) a second sheet of an inorganic glass having a second thickness and a second CTE, and (3) a polymer interlayer adhered between the first sheet and the second sheet including a layer of a first polymer material having a first elastic modulus and a layer of a second polymer material having a second elastic modulus, wherein the first CTE is greater than the second CTE, the second thickness is in the range of from 1 down to 0.3 mm, and the first elastic modulus is more than 20 times the second elastic modulus.
Claims16
A laminated pane comprising:
- a first sheet of a first transparent or translucent material, the first sheet having a first thickness and the first transparent or translucent material having a first coefficient of thermal expansion (CTE1) measured over a range of from 0 to about 300° C.;
- a second sheet of a second transparent or translucent material, the second sheet having a second thickness and the second transparent or translucent material having a second coefficient of thermal expansion (CTE2);
- and
- a polymer interlayer between the first sheet and the second sheet adhered between the first sheet and the second sheet, the polymer interlayer comprising
- a first polymer layer of a first polymer material, the first polymer material having a first elastic modulus, and
- a second polymer layer of a second polymer material, the second polymer material having a second elastic modulus;
- wherein CTE1 is greater than CTE2, the second thickness is in the range from about 1 to about 0.3 mm, the second transparent or translucent material is an inorganic glass, and the first elastic modulus is more than about 20 times greater than the second elastic modulus.
