Things are progressing on my house, next on the agenda is siding.  I will be going with Hardie lap or Smart lap (leaning toward Smart due to ease of cutting, screwing, etc).

Looking at my corners today, I realized the plastic screw ties extend only 3 inches in, thus not leaving room to screw the ends of my siding tight to the wall.  Depending on what trim boards I use on the corners, I will have 5 - 7 inches of siding butting to my corner trim with no way to fasten it...?  Maybe this insn't a big deal, but I would feel better to have a screw within an inch or two of the ends.

Help will be greatly appreciated.

I don't know if this will help you or not, depends on your block configuration. I used BuildBlock forms. They have a 3" x 4" enlarged web section about 1 1/2" from the corner and located half way up the block. I used a hot knife with a custom shaped knife blade to cut a 1/2" deep by 3" wide groove down the block surface. This cut the foam down to the web. I cut 3" wide strips of OSB and screwed them to the enlarged web section. We then nailed the ends of the Hardieplank to the OSB. I used 5/4 x 4 Truwood trim at the corners with the Hardie butting up to the trim.

What form do you have?
smartside is the better siding.
If you will put a bead of caulking behind the peace as you are installing it.
And then caulk the piece to the corner board, that should be fine.
The caulk will hold it in place.

You can also install a piece of aluminum flatstock bent at 90 degrees on the corner and scew in the aluminum

Great advice, thanks for the replys.

I used Logix, great block, easy to work with.

Check that one

Doesn't Logix tout their "corner web" that has the built-in furring strips? Are they sufficient for attaching siding to the exterior at the corners?

Checked on prices this am, Smart is running about 35% more than Hardie...

Is Smart siding that much better? 

Here in middle Tennessee I sell smart side a few cents a foot less than hardie. Logix dose have a corner web that will hold the corner boards.

The corners will hold the trim with no problem, but the web extends only three inches.  I'll use a four inch piece of metal flashing to fasten the ends of my siding (similar to how I fastened interior walls).  Not sure why I didn't think of doing this on the outside... it worked great on the inside.  

I was surprised at the pricing on Smart.  I figured it should be the same or a little less.  I'll shop a little on Monday.   

I used Hardiplank on my house. It wasn't that big a deal to cut and hang. I bought a pair of PacTool Snapper shears to cut it and a set of PacTool siding gauges to help position the planks for hanging. I don't remember what kind of drill we used to drill starter holes, masonry bit maybe, or a grit edge bit. We then used a grit edge tile cutting blade in the jig saw to cut holes for electrical boxes, etc. I used Buildblock forms which have webs every six inches and a reinforced web section at 8" vertical. We blind nailed the Hardi every six inches to the reinforced web sections with spiral siding nails. Holding up good.

The lumber yard guys I talked to before I started the house all said the material cost of Hardi is less than composite wood siding, but installation takes more labor, especially when compared to 16" wide siding panels. Around here Hardi is considered the better product overall, but I'll admit the composite siding I see looks like it holds paint pretty well, and looks pretty decent.

I prepainted the Hardi, two coats, before we hung it. That way the entire front surface, both edges, and both ends are painted to maximize moisture resistance. Next time though, I will paint only one coat before hanging and do the second coat on the wall. There's a lot of touch up painting to be done after it's all hung. More efficient to combine the touch up and second coat on the wall.

Most quality ICFs have furring strips built into the corner blocks. Greenblock has 1 1/2" furring strips 3/4" from the corner.

Logix has a 3 inch furring strip on the corner, but a 4 inch piece of smart trim covers it.  To solve the problem, I ran 10 inch flashing on the corners, (5 inches extending on each side).
