The passage of the electrical circuits can be done in the thickness of hollow partitions, such as partitions gypsum board on metal frame.
In plasterboard partitions, vertical metal furs are pierced with lights every 50cm. This makes it possible to circulate the water or electricity networks in the thickness of the partition.
On your site, mount the metal frame, fix the drywall on one side, then place your insulation.
Before closing the other side, set up your electrical sleeves.
If one side of the partition is still open, simply slide the sleeves or cables by compressing the insulation.
On the partition is completed, drill a hole at the top and bottom and introduce a weighted sheath.
For a horizontal passage, one can have the chance to drill near a fur hole. Otherwise you have to drill several holes... at the risk of weakening the partition.
