Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose ProFold Premium when walls are notably out of plane or when you want the most R-value the fanfold line offers; the 1/2 in. sheet bridges dips better than thinner boards. Keep seams staggered and lapped so the siding lies flat. Combine with house wrap underneath for a full weather-resistant assembly. Fasten through to sheathing so panels do not bow between fasteners.
Confirm local code requirements for exterior insulation assemblies before installation, and use a sharp utility knife carefully when cutting foam panels.
