Steel doesn't require a warranty against structural decay, termites or rot so why use wood?

The posts are for the benefit of other areas besides Canada

You are off on you weight per sq. foot OSB is closer to 3.5" and steel is 2.5# and are light enough that no crane is required.
The underside is pre-finished and serves as a finished soffit, panles are unaffected by water or other ellements, nothing to warp/swell or split.

Our panels come up to 53ft. long, OSB is limited in length

they do not require splines (OSB most common problem - can have leakage problems @ splines)[/quote]Chris,

In your areas, FL & LA, I can see where you are concerned with termites, rot and fungus. I've seen pics of some of the damage the termites are doing to New Orleans. Pretty sad. But here in the midwest I still think you can avoid all of those problems just using the method I mentioned earlier. The warrenty is just a bonus.

Your're right. I should have said 2.2lb foam density. As far as a crane goes, a lot of the time it's not the weight, it's the size. It's hard to handle just about anything as large as 8'X24'. A crane/sign truck is a safe and fast way to do a panel install, especially on some of the sites we work on.

Wow! You can install 53' long SIPs without machinery? Impressive. How wide are they?

The splines in the panels we use are molded in during the process. They are basically part of the rest of the panel.
The foam core in one panel touches the core in the next. Expanding foam gaskets applied within a 1/4" gap in the OSB seals out air and moisture. The gap also helps prevent ridging, especially in roof panels.

I visited your site, pretty nice. I couldn't seem to find much in the way of technical data. I'm kind of a newbie at this computer thing. Where can I find that info?

Thanks,
