How this node works
Performance is defended in the details: the second-layer joints are staggered from the first and filled, and the electrical boxes on the two faces must never be back-to-back, so as not to open a path for sound.
Key points
- First board layer
- Second layer (staggered joints)
- Joint filling
- Mineral wool
- Electrical box (offset)
- No back-to-back penetrations
