Trex Glass Railing
Trex glass railing gives the most open view of any infill, because there is nothing between you and it. Tempered panels drop into the same rails that take balusters.
One rule catches people out. Trex specifies a tighter post spacing for glass than for balusters, so a run laid out for the wider spacing will not take glass without adding posts. Decide before you set the post layout.
The trade-off is cleaning: glass shows every splash. Priced online with live stock. Call (815) 439-3325 before you set the post layout.
