After applying products to the image of the home, you can click the “compare” button to quickly compare the before/after image, or you can use the Snapshots tool to save different design combinations that you can later come back to. Snapshots will also be imported into your Design Report so you can share or print out a full report of your favorite designs.

#2 galvalume (or secondary) is a chemical treated metal that may have a light wavy edge, may be derived from excess inventory, may have a variance in tensile strength, and mostly non-acrylic.
#2 galvalume needs special care before installation to prevent extreme weathering such as black spots on panels.
They are stronger, will not rot, carpenter bee proof, more resistant to fire, capable of spanning further distances, and screws do not back out over time.

29 gauge is primarily used on homes and farm structures, and 26 gauge is more often used on commercial and industrial applications.
