Vapor barrier before electrical outlet?

[Rolle85]

How do you attach the electrical boxes to the studs when the vapor barrier is mounted? Or do you mount the electrical boxes before installing the vapor barrier and then make small local holes in the plastic where the box's holes are?

Do you not have any installation layer after the barrier/brake?

 

[Rolle85]

You mean a framework over the barrier?
If so, how thick should it be and should there be insulation in those sections again?

You mean a framework outside the barrier?
If so, how thick should it be and should there be insulation in those sections

The most common is 45×45 lying studs with insulation between them inside the moisture barrier.

 

[Rolle85]

Inside the moisture barrier? You mean afterwards otherwise you can't install the electrical boxes?
In these compartments, I mean, or do you leave them empty and just put gypsum over them?

If only one had that.
No installation layer exists in my 70s house 😅

 

[Rolle85]

But the installation layer in the picture, what should they be in the compartments? Completely empty?

In these sections, I mean, or do you leave them empty and just put drywall over them?

In that picture, there's plastic installed + studs and boxes outside. On top of this, you might put plywood and then drywall.

However, the horizontal seams on the plastic don't seem taped?

Empty or most commonly you cut insulation

 

[Rolle85]

Okay, so the compartments are empty

Ok so the compartments are empty

It is clear that you insulate, that is my perception. It is much nicer to pay for insulation once than to pay for heating year after year. You get a quieter, more comfortable house as a bonus.

 

[Rolle85]

Sure?

However, the horizontal joints on the plastic do not seem taped?

It also looks like it is jointed in a way that any potential moisture runs down into the insulation. This joint should be taped, especially if he wants to skip insulation in the installation layer.

Yes, you insulate the installation layer. Why wouldn't you do that? It provides better insulation value in the wall without losing floor space or increasing the building area.

Inside the moisture barrier? Afterward you mean, otherwise you can't get the electrical boxes in, right?
In these compartments, do you mean, or do you leave them empty and just put plasterboard over?

In the installation layer, you place insulation and then just boards over it.
