ZS SPAN INSTALLATION MANUAL FOR RAIL-BASED APPLICATIONS - U.S.
Along the axis of the Interlock, large arrays also need a physical gap after two Thermal Expansion
Joints. For example, a North-South drop-in, Landscape orientation, might require a physical gap
approximately every 100 feet. This would be approximately every 18 module lengths, depending
on the module.

4.5 Roof Zones
Roof zones identify the interior, edge and corner regions of each designated roof plane. This is to
take into account varying wind pressures as the wind passes over different areas of the roof. The
maximum allowable Cam Foot spacing may be smaller in edge and corner roof zones.
