Don't forget with the furring (especially with metal hats), it's all added costs. :( Metal SIPs themselves aren't inexpensive either.
Chris:
What is the maximum span metal SIPs can do? I guess I'll see pricewise if I can substitute it with OSB SIP roof panels instead...
And does anyone know of any installers they'd want to recommend? |

Leon; don't forget to add the cost of the crane, soffit and facia when comparing to OSB vs. steel, none of which is needed for steel SIPs

You mean soffits for overhangs?
And fascia as in the siding?
Fibercement panels is roughly ~$1/sqft... |

cathsand,
If one use it one will have to figure out how to close the foam end of the panel off and allow the rain water to drain properly. The attached detail is usually how a panel of the sort is used. |

Leon;
yes underside of steel SIPs are a finished product. Facia - as in the: cap the end of the overhang, is also finshed with the steel SIPs, as you said" It all add's cost" fibercement @ $1.00 sg. ft. plus installation , plus paint, plus labor, plus long term maintenence................ it all ads up! |

So if a steel SIP panel is placed on an ICF wall, let's say 18" of overhang, that SIP panel can be left alone without any Hardiboard or finishing hardware? Do you have any pics of how that would look? |

Chris, that looks really pretty. I am still wondering if I could do a SIP roof that could look good enough that I wouldn't need to put another roof on top of it! |

In regards to that picture, are all those ridge beams necessary or is that more of an aesthetic thing, and what are they made out of? Does that paint stand up to intense Arizona UV's? So in theory, it would only have to be repainted every 15-20 years, correct? If one wanted to attach gutters to that SIP, do the SIPs have any steel beams/channels INSIDE of them to use as an attachment point? Is the steel galvanized or just basic steel that is painted? Thanks for answering all my questions! I really appreciate it!  |

GMC Sierra LED DRL Strips for Those beams were for aesthetics,
Since the Arizona sun would not likely hit the underside of a roof overhang much, there is not mutch to worry about? Steel skins come in either G-90 galvanized/painted or Galvalume /painted Facia is 24 ga. steel very adequate to support gutters( there are no internal supports in the steel SIPs they are purely structural on their own) |

What is the difference between Galvalume and G-90? If the fascia is 24 Gauge steel, how thick is the rest of the SIP? Do you have any pics where the SIP connects to a ridge beam inside of the home? I assume that the same SIP screws attach to the ridge beam as they do on the ICF wall. THANKS AGAIN! |

Galvalume is a zinc/aluminum alloy coating and G-90 is hot dipped coating....................... Sip skins are 26 ga. |

No it is not needed on a wood beam or a steel box beam either, most of the time the steel box beams have a square edge top. Steel box beams can be site built or ordered pre-assembled from Met-Wood. www.metwood.com |

Chris -
On a steel roof SIP, does it have the same problem that an OSB SIP would have? In regards to the panel joints having air spaces in them and then warm moist interior air meeting cold exterior air, causing condensation to form.

Lbear;
our steel SIPs are a "friction fit" foam to foam contact , designed with no gap. In addition; metal SIPs will not shrink or warp like wood, as wood ages it dries out and shrinks, a wood joint that is tight when first installed can seperate in just a few months. OSB is not made with close tollerance and can vary by 1/8" on a 4' x 8' sheet and still comply with industry lumber standards. Steel is presicion made and consistent    |

Speaking of OSB wood SIPs, this unfortunate homeowner is having shrinkage in his wood SIPs and it is pulling apart his T&G panels.  |

The one area where steel SIPs would not have a foam to foam contact and where they would have a gap would be at the ridge beam peak:  |
