Building window reveal

[nosslo77]

We are in the process of building a Vision80 house from Västkuststugan. Small question marks keep arising all the time. The latest issue concerns the windows.

Behind the drywall, there is a piece of plastic protruding from the vapor barrier to the wall, which would be enough to cover the entire window recess (http://4.bp.blogspot.com/_SfzF_cWC6RM/SpG8RVnzp3I/AAAAAAAAA8s/oYE0mFToDWg/s1600-h/DSC03786.JPG). Should/must it be used for the recess? There is no risk of moisture damage there, is there? If you insert the plastic there, you can't use adhesive to attach the saddle. I don't want ugly screw holes there.

I'm asking the question here since I rarely get good answers from Västkuststugan's factory.

Thanks in advance

It is more stable than one might think. We rarely work on it when it's on pallets, and then we secure it to the outer walls. But it's probably still not something the work safety authority would like. ;-)

Should/must it be used for the reveal. There's no risk of moisture damage there, right?

The vapor barrier is supposed to prevent humid indoor air from penetrating the wall structure, and it can do so through the reveal just as well as through the wall itself, right? So if it's supposed to be properly airtight, the reveal should probably be plastic-covered as well.

I understand that you want to avoid screwing through the reveal boards. I know I've heard about people who assemble the reveal boards into a "box" which they then glue to the frame. Maybe that could be an option?

That sounds like a good idea. I'll try it on one window and see how it goes.

Thanks

Yes, otherwise you can nail the smyg with brad nails (nails with a small head), putty, sand, and dab on with paint

Depends a bit on what kind of smyg you plan to use...

The window recess and window sill are made of lacquered MDF board
