I am in the process of building a soundproof partition wall in our courtyard. The wall consists of 70x70 mm posts with 70 mm fiberglass insulation in between and 25 mm wood concrete on each side to minimize noise as much as possible. We want horizontal 21x45 slats with a 5 mm gap in either pine or cedar on both sides in the end (see image).
I am now a bit unsure about how to proceed with the construction. As I see it, there are three possibilities:
Screw the panel directly onto the wood concrete
Staple on wind barrier paper to protect the construction against moisture. Then screw the panel
Staple on wind barrier paper, mount battens to create an air gap, and then screw the panel
What would you do? Thanks a lot in advance!
Currently 70x70mm pressure-treated posts, 70 mm fiberglass insulation, and 25 mm wood concrete. Goal image
