Olympia vs. The Competition

Olympia’s PBR Roof System
(Purlin Bearing Rib)

Olympia’s PBR  roof system provides a full overlap, preventing water from leaking into the building during storms when strong winds force rain against the overlap. Where the sheeting overlaps, the panel runs all the way to the bottom of the corrugation and along the bottom like are versed “L.” The top PBR panel resembles a “Z” and overlaps the bottom panel providing additional strength as well as protection against leakage.

Competition’s “R” Panel Roof System

Some of Olympia’s competitors use an “R” panel system. The overlap only extends 1/3 of the way into the corrugation of the connecting sheet and is not sufficient to give strength to the joint.

Water can build up in the corrugation where the panels overlap. Strong winds can push this built up water through the overlaps and into the building causing tremendous leaks.
