What is the basic method and how great a span can a SIP panel handle? Do steel joists make the span with SIP panels placed perpendicular to the joists, or do the SIP panels make the large span by themselves? Does anyone have a reference for span tables for SIP floors?

A 6" panel wll span 8'. You can visit most manufacturer's web sites and get specific span tables for the product you intend to use. The support can be anything that is engineered to support the load whether you are using lumber, steel or component. It really depends on what is below. There is a pier and beam post that you can search for on this site which gives some cost calcs.

Jelly; A 6" Steel SIP will span 12ft. making the large span by themselves ( no joists), with support beams/walls @ every 12 ft. My own office uses a steel for a 12 ft. loft ,we have pleanty of weight on top too, filing cabinets, etc. Steel SIPs over a pier system works great as they have a built in vapor barrier I can e mail you directly the span charts if you like, they are too large to post

Chris, yes send those span tables, that would be great - I'll email you directly to remind you. Very intriguing. So if the steel panel can span 12 feet then you've got joist and subfloor practically all-in-one, right? I guess the span tables will show me whether it will take a live load to support steel framing/bathtubs/washing machines... How about putting a hardwood floor directly on the steel panels? And how about putting thinset and tile directly on the steel? Any issues with mounting electric radiant heat in the thinset under the tiles?

Matt; just e mailed charts to you, I would not reccommend direct floor attachment to steel skin, you will need a suitable underlayment, hardwood adhesive would not be approved for use nor would thinset adhere to steel. If you have living area below, I would not recommend any panel be used as you will have no mechanical chases. steel framing, tubs and appliances are dead loads radiant heat - check wth mfg. some do not allow well insulated floors underneath.

Posted By cmkavala on 11/17/2007 10:37 AM steel framing, tubs and appliances are dead loads [/quote] Yes of course, you're right. So the 40 lbs per sq ft rating in the span table is a standard domestic live load, hence the 12 foot span? I see - a good application for this would be, for example, over a crawl space or even a basement.
