Depending from which way the prevailing weather originates, the panels should be 
orientated so that the overlaps of the top skins face away from the direction of the 
prevailing weather. 
When defining the panel layout the starting point is based on looking from the gutter 
end towards the ridge. 
Delta Panels insulated roofing products are designed to be able to be installed from 
either right to left or alternatively left to right.
When ordering a roof panel the length designated is always that of the top skin NOT 
the length of the cut-backed bottom skin. A right hand cut-back would be defined 
as a panels starting on the right hand side of the roof with the subsequent panels 
being laid from right to left.
