Vertical joints need to be insulated, either with a special insulation, or foam. For fastening, special screws are used.
Vertical installation is very similar to horizontal. Installation from the lower corner of the wall begins, from the base. The vertical series of the required height is mounted. Only then the row is attached to the basement with self -tapping screws, and the panels are also fastened to each other. Then other vertical rows are laid out.
