Hello everyone,
I am currently working on my interior construction. My wall is a timber frame wall with a 6cm installation layer attached on the inside.
As far as I can see, the carpenters have screwed the installation layer vertically only at the points where there is also a wooden beam running in the wall.

I need to reinforce the installation layer in a few places because built-in furniture will be installed there from the inside, and these wouldn’t really hold in the 15mm OSB.
I first tried using 70mm screws so as not to pierce the vapor barrier, but that doesn’t hold...
With 100mm screws, the reinforcement sits rock solidly.

The question now is, is it a problem that I have penetrated the vapor barrier from the inside? There are already a few spots. However, the component lies flush on the inside + the screw in the hole.

Thanks for your feedback.
Chris
