Insulation/interior finishing

So….yesterday Richard and I worked with the 11-1 group (those who came to class that is!) and we installed the gyproc in the new class.

Firstly, thanks to all who participated!  I hope you all learnt something and you had fun!  It was work well accomplished for the school and your efforts will be appreciated!

Secondly, I expect you will apply what you learnt to your carpentry careers.  As I expressed, most of you will be working in interior finishing for the bulk of your lives as carpenters, especially for those of you working in renovations.

In the meantime here are a few photos.  Again, congrats.

    Hi again John, so here’s a debate I’ve been part of these past few days.
    I had to renovate an old and I mean very old building when I ripped down everything I noticed full wooden blocks of lumber as the exterior “sheathing”. Anyhow I noticed that on that there was black roofing paper. This we never covered in class. So when I framed the inside walls (I had to because there was no insulation..) I replaced and re-installed all the black roofing paper then framed everything at 24 o/c then insulated with batt and finally air barrier.
    so I have two questions for you here:
    1; why the back roofing paper? My theory is to shy away water so if there is a leak it would not attain the studs…
    2; when framing EXT walls after the polymer barrier can we apply our gypsum right on it or do we have to install cross lumber like 1″x3″ for example? Again my theory is that we do have to install the cross backing so we create air circulation but I don’t remember why its important! And if we don’t, if we do install the gypsum directly on the air barrier is that a problem?

    John I want to thank you in advance for all your time.
    Let me know I there’s a way to send you pics.
