Multiwall polycarbonate sheets are level on both sides. Based on my previous short article you must be utilizing sheets with UV defense on one side.

The next part is the U which is sometimes called a J. This addresses the leading as well as the bottom of the sheets. The purpose of this account is to maintain pests, moisture as well as dust from the networks. The U below the sheets should have small openings (1/8") roughly every 2'to allow for drainage.
The next component is the F accounts. This is made use of making corner. If this part is not readily available we in some cases just put U's outside sides of our sheets and butt them up tight together to earn a corner. Some suppliers offer a ridge account from polycarbonate.
