What is the difference between punched and unpunched ColorGard?

Punched ColorGard is slotted every 4” (10.2 cm) on center for seams spaced accordingly (divisible by 4”),where as Unpunched ColorGard accommodates any seam spacing. Use with all snow-compatible clamps or brackets. Both install in 7'8" lengths. 


If using Punched ColorGard, it is not recommended with exposed-fastened profiles.
