Plenum PanelsTM span further than solid CLT panels because they are not limited by vibration.
Spans for both PP1 (single plenum panels) and PP2 (double plenum panels) are calculated for typical sheet thicknesses and typical panel.
The spans are for simple span loading and assumed fb of 1,250 psi and an E of 1.2 x106.
An equivalent web thickness of 25% of the sheet width is assumed. Dead loads include panel weight.
