Whomever you are buying your SIPs from should have this table to help you decide on the layout. They should have tested the panels and should be able to tell you whether the Load is too much. The span is not the problem, the weight is. Typically a floor is L/360 and a roof is likely to be no stiffer than L/240.
Hope this helps. |

Ivan;
a double 2 x 10 spline is the same as 2 x 10 joists @ 24" oc, at a 12 ft. span would also provide the same support, unless you just need the extra insulation, I don't see the point of the SIP floor |

If your application is an 'ordinary' residential one then your design is ok. Typical residential floor loads per square foot are 40lbs live + 10lbs dead(floor framing) + 5lbs dead(wall framing) for a total of 55lbs. If you are going to use tile as a floor finish, the deflection should be L/360 or it will crack, but if your SIP can support 62.8lbs at L/240 then you are probably ok for tile if you add underlayment. However, if your application is commerical you may be very under designed. |

Simon is right and what I meant by typical floors need to be stiffer. We use a lot of tile in the Southwest and the grout is the problem. You proivde a floor with less than a L/360 and you are asking for problems. I will look at the table and get back to you...
