Max-Rib Commodity/Max-Rib Liner

This panel has a 10-year warrantied economical panel that is ideal for interior applications such as liner panel or basic shade and shelter applications.

Max-Rib with MoistureLok

For non-climate controlled buildings, field applied condensation control has historically been a necessary and labor-intensive construction element. Multi-Rib (PB), MasterLok-90 and Mirage panels are available with factory applied MoistureLok an anti-condensation membrane. The end result is an economical and non-labor intensive condensation solution. MoistureLok’s membrane provides a medium for trapping moisture and holding droplets in place until conditions go back to below the dew point. At that time, the moisture is simply released into the atmosphere in the form of natural humidity.
