Hardiplank siding installation
When installing hardiplank siding over 7/16 osb do the butt joints have to meet over a stud? I know this is probably a stupid question but while reading the installation information it is pretty vague. Any advice would be appreciated.
Thanks,
Bill

You need to get the factory hardie install info.
Seems to me they once allowed breaking between studs but changed their recomends. But then that's just how I remember it.
Also there are the off stud joiners to consider which are end clip hardware.

As of Aug 2011, James Hardie states that hardiplank can be installed directly to 7/16" osb for HZ5 and HZ10. They do recommend nailing into studs. The butt joiners would still be a good idea in my opinion.

I just finished installing 2000 sticks of fiber cement by myself.
Read up quite a bit first and all the mfg install manuals said for joints to be over studs and to use siding nails or 1-1/2 or longer roofing nails. You did not say what type of nails you are using - siding or roofing?
Of course, I ignored all that advise, and installed at random nailings, generally 12 in to 20 in depending on how tired or how high the siding was. However, was NOT nailing to osb, was nailing to 23/32" 13 ply baltic birch sheating with 1-1/4" nails.
Did do a test first - on the birch, the fiber cement broke before the nails pulled out of the siding, on osb the 1-1/4 nails pulled out of the sheating so would go with over the studs or longer ring shank nails on osb..
Suggest you do your own test with a sample, if the siding breaks before the nail pulls, dont bother trying to hit the studs.

Better to make it a rainscreen: Apply 1x3 battens over the wrb by screwing into the studs. Then nail the siding to the battens.

Butts (post #206998, reply #7 of 12)
One alternative to locating the butt joints on a stud is to let them land anywhere and use 1-1/4" screws to secure to the sheathing. Nailing within 3/4" of the end of the panels often results in broken corners. With easy-to-install star-drive screws, you can put them 1-1/2"-2" away from the end of the panels, no broken corners.
Don't forget the flashing behind the butts!!

Those are some large looking heads.
And would they bore through and flush up in fibrecement?

Heads (post #206998, reply #10 of 12)
Yes they do pull up flush to the surface of the fibercement. With the cutting nibs under the head of the screw and the knurled shank that reduces drag, the head sets flush. The head size is typical of any wood screw in similiar length. We have also used this method at the house corners, with wide trim there is not any backing to nail to, the screw-sheathing method works!
Dan- When nailing the butts to a stud, the nail needs to be within 3/4" of the end, or it's a miss.... With a screw to the sheathing, you are able to move back a little and still hit the target (sheathing). A nail into sheathing only is useless in most cases.
By not hitting the studs with the butts, alot of cutting is eliminated, which is a GREAT thing.

Why would using screws let you secure the sheating farther from the ends than using nails??

I'll bet I can drive four nails using my siding gun in the time it takes to drive one of these screws. And I'll bet I can roll paint onto a couple of square feet of siding fastened with flush sitting nails in the time it takes to spackle the heads on the screws. So for time efficiency a nail gun will win out every day. Not to say that screws don't have their place. Like for fastening the battens on a rainscreen installation.
