  • Multiwall polymer sheet with cells having liquid affecting solar and light transmission
    Patent number: 7614186
    Abstract: Disclosed herein are multiwall sheeting and articles comprising multiwall sheeting. In one embodiment, a multiwall sheet comprises: greater than or equal to three polymer walls (e.g., comprising a first outer layer, a second outer layer, and an inner layer), a transverse layer, and a liquid. The liquid is located in cells formed by the transverse layer and the walls. The multiwall sheet has a first visible light transmission and a first direct solar transmission. A second multiwall sheet has the same materials and the same design as the multiwall sheet but with no liquid, and has a second visible light transmission and a second direct solar transmission. The first visible light transmission is greater than the second visible light transmission and the first direct solar transmission is about 63% to about 70% as determined in accordance with ISO 9050.
