What Bellingham's climate asks of a vinyl panel
Bellingham logs 4,845 heating degree days most winters, plus 78 on the cooling side come summer, a two-sided load exterior cladding has to shrug off.
Cold Bellingham winters make vinyl more brittle to handle and fasten correctly; hot summers are when reflected-heat distortion tends to show up instead.

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?
