Frequently Asked Polycarbonate Question

Moisture can gather in the panel’s flutes

 Q: Why should I install multiwall polycarbonate panels in a vertical direction?

A: Moisture can gather in the extruded ribs or flutes of a multiwall sheet. Vertical orientation allows for water accumulation to drain. When used for a roof application, the slope should be at least 5 to 10 degrees, never level. Remember to drill weep holes if you seal the end of the panel with a U-channel.
