   You call my thread a diatribe and then want me to help you ???

   Dang - It's a good thing I'm such a wonderful guy.

   (-:

   I generally like to cut 14" deep floor members off at about 21'. (The 18-to-1 rule of thumb) Since you're just barely over that, and if the vibration formula comes up with more than 15, it wouldn't bother me.

   I'd definitely glue and screw the subfloor. That seems to make a lot of difference with I-joists.

   Boss,I would never call your thread a diatribe. In fact, I'm offended that you would even suggest that.Anyways, do you think that there is a significant difference between nailing and screwing?As always, I appreciate your input.

   "I would never call your thread a diatribe."

   Well, ya did - In your first post in this thread. Hurt my danged feelings. (sniff)

   "Anyways, do you think that there is a significant difference between nailing and screwing?"

   Yup. But I'd have to admit that I don't know exactly why.

   Every one of the I-joist manufacturers recommends screwing over nailing. Some of them even have diferent span charts for glueing and screwing vs. nailing.

   It may have something to do with the fact that it holds the top flange more rigidly. But like I said - I don't know for sure.

   That's an interesting comment Boss. I wasn't aware that spans could be increased with glueing and screwing vs nailing.

   I have a question. Do the spans also increase for glueing and screwing over glueing and nailing? Or, is the glue the difference that increases the span?

   All the books and such that I have on I-joists are at the office. I'll take a look monday and see what I can come up with.

   I'm working on a job with the plans spelling out glue & screw the deck.  What type of screws are used?  Deck screws?

   "What type of screws are used?"

   If you have a collated screw gun, they sell subfloor screws for that purpose.

   If not, deck screws would probably be fine. Anything but drywall screws.

   Boy am I embarassed, comfortably living under a rock all these years.  I probably looked right at "subfloor screws" and it just didn't register that they would be ideal for use on the subfloor.  *chuckle*
