A sheathing system that envelops a building structure is provided, combining lightweight structural layers and a high R-value insulation layer. The insulation layer includes a coated insulation product with a reduced fluorinated blowing agent concentration, while maintaining acceptable thermal properties. The coated insulation product includes a foam product that is coated with a barrier coating. The barrier coating includes a polymer having a minimum degree of crystallinity and at least one additive. The collective layers of the sheathing system offer the benefits of decreased thickness, reduced weight, improved thermal insulation, improved structural strength, improved nailability, improved fire performance, and enhanced energy efficiency.
