Unpunched ColorGard® is the most versatile and easy to install, when used with the S-5!® VersaClip™. Unpunched does not need holes, as the VersaClip™ accommodates any seam spacing. The unpunched configuration works well with VersaBracket™.
Unpunched is the right choice when the roof is laid out with untrue seam width or when the seam width is not divisible by 4. If in doubt, use unpunched.
