What Firestone's climate asks of a vinyl panel

That Firestone swing is exactly why installers leave slack at every opening rather than fastening panels tight.
5B is the IECC climate zone for the surrounding county.

Before you sign, ask about the panel itself
- What thickness, in mils, is this panel, and does it carry an independent ASTM D3679 certification listing?
- Is this standard vinyl or insulated vinyl, and if insulated, what R-value is certified under ASTM D7793?
- What wind-load rating is the product certified for, in miles per hour, and how does that compare to {county}'s wind risk?
- Will the installer leave the manufacturer's specified expansion gap at trim, corners and openings, or nail tight?
- If the color is a dark shade, is it separately certified for color retention?
- Does any wall face reflected sunlight from a neighboring low-E window, and has that been accounted for in the material choice?
