Eldon, the largest I have ever seen or been envolved with are 8' x 24' and 46" x 54' x 12", I have been involved with arched sips that need to be built in a custom form, it is not an economical ordeal |

The largest SIPs are Metal SIPs and their length tops out at what can fit safely on a 53ft semi truck. The thickness is limited by how wide the SIP making machinery and presses can be opened up which is usually 10-12 inches. Arched SIPs are a completely custom item and the ones I've witnessed being made required custom formwork/molds and are hand built. |

Simon;
I have shipped 54 foot to Texas by using a 54 foot trailer with no head board, you can slide the panels forward 1 foot and still be legal. I also know of 60 foot panels being built and shipped with special permit |

If a roof span is 42 feet (ridge beam to wall w/overhang), would it be better to just do TWO panels at 21 feet each instead of one huge 42 long panel? The two panels could attach/meet at a beam that spanned that 21 foot section. |

Kingspan has a certain way they join two panels to cover a long span. |

It is stronger to do one panel and requires less fasteners |

Let's say one was going to attach that 42' long SIP at the 21' mark anyways since there is a ceiling/roof glulam beam there. So there would be 3 attachment points (ridge, 21' span, outerwall). I don't understand how one 42' long SIP is stronger than two 21' long SIPs, on the same span area. Please help me understand?? |

With most construction materials, a single component is usually stronger than a two piece………………………….
For example: on a standard roof or floor sheathing deck the week point is where the two sheets of plywood butt and are fastened on a framing member. Common and good constructions practice is to offset and stagger the joints every 4 ft., so as to help overcome all the weak points occurring on one member.
An 8” SIP with a 20# load will span 22.43 feet when connected at two points, when a longer panel is connected at 3 points the maximum allowable span becomes 26.22 feet , or if spanned less would increase the maximum load |

A structural member can usually span further if it is multi spanned rather than singlely spanned because each span assists/counteracts the others loading. For instance, in a double spanning member with three supports, the center support becomes kind of a fulcrum point and a downward load on one side becomes an upward force on the other to a degree, allowing that member to span further. A single spanning menber doesn't have the advantage of the counter loading. |
