Multi‑wall polycarbonate panels are engineered for durability and performance—but most failures don’t come from the panel itself.

​

They start at the edges.

Unprotected or incorrectly sealed flutes allow moisture, dust, insects, and spores to enter the panel.

Over time, this leads to:

• Fogging and condensation

• Algae and mold growth

• Reduced light transmission

• Premature panel degradation

This professional guide shows you how to seal panels correctly the first time—using the same methods trusted by manufacturers and installers worldwide.
