Non-Stick Tape is attached to the surface of the caulking joiner. The caulking joiner is used to maintain the quality by ensuring the even width and depth between the panels. Filling the caulking joiner with color matched caulking helps camouflage the joints between the panels.

Caulking is not necessary between the panels with a vertical application. As a result, vertical applications use much less caulking compared with horizontal application. This leads to better quality ventilation, water resistance, lower maintenance and an overall more sophisticated look.
