Abstract
In one embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a non-uniform cell density. In another embodiment, a multiwall sheet can comprise: non-intersecting polymer walls comprising outer layers and a transverse layer and/or a divider. The transverse layer and/or the divider extends from one of the polymer walls to another of the polymer walls to form cells. The multiwall sheet has a non-uniform cell density. In yet another embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a different number of inner layers, transverse layers, and/or dividers, in different portions of the sheet. The multiwall sheets can be used, for example, in a naturally light structure.
