Several years ago we built a house with SIPs and used cedar lap siding nailed into the SIP skin with galvanized finish nails. That was a big mistake, but the home owner was acting as the general contractor, and we tried it. At the time the nails seamed to hold. Fast forward about fore years, and the nails are pulling out, or pulling through the cedar, and the siding job looks terrible. The owner now wants to replace cedar with Hardi, and has been researching how best to fasten to SIPs. He has been advised by industry reps to install 3/4" firring strips every 16" with screws, and then put Hardi plank on with nails as normal. Ring shanks would be preferrable however. I have never seen galvanized ring shanks.
Several years earlier, we did a similar project but used Hardi plank siding to begin with. IN this case we pre-drilled and countersunk screw holes, and screwed the siding on with galvanized sheetrock screws. We stacked about six pieces of siding on top of each other to drill the holes all at one time on 16" centerd, and then fanned them out to create a slight divit for the counter sink with a masonry bit of the proper size. That job looded good then, and still does.

I've never met a man that was owed as much as he thought he was.
Thanks for the uplink. I printed it and will give it to the home owner to do with as he wishes.
we just did two SIP houses with Hardi and decided to take our chances with blind nailing.....so we used galv roofing nails on 8" spacing into the OSB.....the few that we had to rip back off during instalation did not come off easy.....fast with a roofing nailer and no face nails ,,,,,,,,
homedesign,
With the extra effort required to put Hardie Plank over SIP's have you done enough research about other siding options? What would the cost differental be compared to say stucco, brick, or stone? Those aren't something that you can get one bid and have an answer. stone masons, brick masons stucco installers come in all sorts of prices and I found the most expensive don't mean that the best job is done.. It's just that those people have a broad enough network of customers to command the highest prices..
I found that working with stone was something that I enjoyed so my only cost was material costs.. compared to the finished costs of say cheap vinyl siding stone was a wash if I did the labor..
I found that out the hard way.. I had a small section done by a contractor and he gave me what he called a loss leader price of only $3000.00 He was right, other bids were over $5000.
Like any well informed consumer I had read about stone work to educate myself what to look for.. and watched while his crew worked to ensure myself that I was getting a good job..
I'll skip all the gory details but having read just one book and watched his crew at work, I realized that stone work is really easy.. The only hard bit is the weight of the stones themselves and we're talking about 30# on average here, not the end of the world.. I also found that I could be much more organized than he was and instead of picking up a stone several times looking at it and setting it down I could look for an approiate sized stone, spot it and over 90% of the time be correct. What took him days to achieve I did in 3 hours. I also put more brick ties in and did a better job of keeping the morter about the same size throughout the project..
I'm actaully extremely proud of my stone work. So if you compare the cost of say stone to the cost of installed Hardie plank we're likely to be inside the same budget.. yet stone is something with far higher resale value and appeal..
Frenchy,
I am working on a SIP house with stone veneer. I really like stone.
I am also considering SIPS for my personal home which will be in a historic neighborhood where siding is the only option. Actually cement fiber siding is mandated.
Just curious how others have met the Hardi - (fastening)guidelines with SIPS
homedesign,
For that reason and a couple others I've decided that should I ever build another home it will be ICF rather than SIP's for the wall.
With ICF's you have a place to screw fastners in every six inches with most ICF's. In this case, Hardie planking wouldn't be much of an issue,, simply the cost differance between nailing and screwing..
