The Low Rib panel is relatively easy to install. Simply lay your first sheet on the opposite end of your building of the prevailing winds and follow the recommended fastener pattern to the right. The second sheet can be laid with one rib overlapping the first panel, as per the picture to the right, and follow that pattern for each corresponding panel.
