I would not use the panels for your wood strips. I would use the mullions.
1. Create a curtain wall.
2. Select it.
3. Edit Type.
4. Change the Construction parameter "Curtain Panel" to "Empty System Panel: Empty".
5. Change the Construction parameter "Join Condition" to "Vertical Grid Continuous".
6. Change the Vertical Grid parameter "Layout" to "Fixed Distance".
7. Change the Vertical Grid parameter "Spacing" to whatever value is appropriate for your wood strips.
8. Change the Horizontal Grid parameter "Layout" to "None".
9. Change all three Vertical Mullions parameters to your wood strip family.
10. Change all three Horizontal Mullions parameters to "None".
Note: You may get a warning after you click okay, telling you that some type driven grid lines will be deleted because you've changed the type. That's fine. Just click to delete the grid lines. They're the horizontal ones you don't need.
Note: Number 9 assumes you know how to modify an existing mullion or create a new mullion to represent your wood strip and load it into your project. If you haven't done that yet, you can just select one of the default mullion types. In this picture I've left them on the default type and applied a 6" vertical spacing...

Good luck,
