Punctured vapor barrier

[Guybrush666]

I came to the realization now that "we" when "we" put up renovation plasterboard on top of existing plasterboard used screws that were too long so we have perforated the vapor barrier throughout the house.

In hindsight, we should have glued.

How bad is it? Do we have to tear everything down? Or is it that as long as the screw is still there, it's not good but it works?

How would an insurance company view this in the event of future moisture problems? This would not be considered professionally done and we probably won't get any insurance money for it?

The walls consist of:

Wood paneling
50 mm mineral wool slabs with a vapor barrier layer
Frame construction
120 mm mineral wool slabs
Plastic foil
13 mm plasterboard
6 mm plasterboard

The ventilation in the house is good with mechanical exhaust and fresh air vents at all windows.

Fun with houses!

The renovation plasterboard is well screwed into the studs just like the first layer of plasterboard?

The renovation plasterboard is screwed into the studs just like the first layer of plasterboard, right?

A communication error has resulted in 900mm renovation plasterboard being installed on cc 60 studs, so there is also plasterboard screwed into plasterboard.

A miscommunication has resulted in 900mm renovation plasterboard being installed on 60cc studs, so it's even screwed plasterboard on plasterboard.

Hmm. I can't answer if this could cause problems with the vapor barrier, but I'm doubtful about how well it will hold where it's only screwed into plasterboard?

Edit: my guess is that it works as long as the screw stays there

If you remove all the screws, you might have a problem, but as long as they stay in place, nothing will happen.

The majority of all houses have a punctured vapor barrier and they remain standing, as does mine.

The majority of all houses have a punctured vapor barrier and they are still standing, as is mine.

They naturally do not. The majority of houses with vapor barriers have it a bit inside the wall…

 

[Isakare]

Of course, they don't. The majority of houses with a vapor barrier have it a bit inside the wall...

There are probably more houses with the old design than new, like all houses over 30-35 years old.
And almost all the old ones have a punctured vapor barrier, it's enough when you nail up a picture.
The plastic a bit inside the wall is a relatively new phenomenon, I guess it became widespread about 15 years ago.

To TS: Living in a BR townhouse from '92, single gypsum with plastic directly behind, punctured in many places. Good ventilation via an exhaust air heat pump. There are no problems with the houses at all (30 units). In another similar area built at the same time, there are problems with moisture and mold (ownership). Some have replaced the exhaust air heat pump with a pure electric boiler when it broke down because it's cheaper to purchase, and then didn't provide the house with ventilation. Then they encountered problems.

And like, all the old ones have a punctured vapor barrier, it’s enough that you nail up a picture. The plastic a bit inside the wall is a fairly new phenomenon, I guess it became widespread about 15 years ago.

Strange, because my house which is 20 years old has it, and it wasn't new then...

And I would guess that most houses don't have any vapor barrier at all. It probably came around in the 80s?

Probably built differently at that time, I had it in my house from -66.
