PBU Panels should not be installed on a roof that is less than a 1:12 pitch. When this panel is installed on pitches less than 1:12, heavy rainfall may lead to water accumulation and possible leaks.
PBU panels offer the same look and coverage as U Panel, but includes an extra "leg" on one side of the sheet. The PB stands for purlin bearing, and is designed to go against the purlin or substrate with the lapping rib going over the top. This aids in installation in holding the sheet stable as screws are applied. Note: the side with the extra rib must go under the lapping side.
