I am building a summer, someday retirement house on the coast in nova scotia.the view is 240 degrees, so my wife is enamored of a round house to best appreciate this. The roundness is appealing from a wind/hurricane resistance point of view also.
Some of the round home manufacturers will sell just the roof components, so building the walls quickly and tightly with SIPs and placing the roof structure on that would seem straightforward. I would think roof panels could be cut with precision in the SIP factory as well. Has anyone done something like this in SIP construction?
Thanks! |

They can be done, in flat multi-faceted sections, the most I have done is an 8 sides. Depending on the design you may need a center bearing point or a center "ring" bearing point |

SIP walls for a building of this type would work quite well. Cutting "pie" shaped roof sections out of rectangular SIPs is quite wasteful and labor intensive. The use of SIPs in a roof of this configuration would not be very efficient. But don't let me discourage you. |

Jeff,
I would agree that there could be a great deal of waste on this roof configuration. However,
as a designer, the challenge would be to design the project in such a way as to reduce the waste to
a minimum. Can it be done? I don't know. But it would be interesting to try. |

Although I like metal skinned SIPS more so than OSB, it appears to me that there would be less waste using OSB SIPS for the pie-shaped roof pieces. I think using metal SIPS that have a male and female side would result in more waste. However, with OSB SIPS, a panel could be cut in such a way that both pieces could be used for a roof panel. Much less waste since the cut offs could be used. Am I missing something here?
Also I think that one can more so approach a circle for the walls by using smaller width panels. Are curved panels at a specified radius readily available? Maybe it would be prudent to explore other alternative building systems that do not depend upon factory cuts. In other words, use something flexible that can be molded in place to the desired shape like concrete/foam/concrete (CIC) to build the walls and roof. This type of system would also be very strong in high winds if properly reinforced. Using a dome shape for the roof could eliminate the need for beams under the roof. |

thanks for responses. the kits i have looked at are not truly round, typically use 4' wide panels to make and almost round polygon. so the walls and floor in SIP should be straightforward. i thought that cutting a rectangular panel into two pie shaped pieces might give a roof with minimal wastage. |

Not the way it is done with metal as no one is going to make pie shaped panels with m-f , but the way we have done it in the past is to: square cut the pie shaped pieces then join together with brake-metal (stitch screwed) top and bottom |

One cannot cut a 4' wide panel into two usable roof sections unless the wall segments are less than 4'. Because each roof section must sit squarely on a wall segment. If one were to cut the roof sections out of a jumbo panel (8' wide) one could produce two usable roof segments, but there would still be considerable waste. I have calculated an average waste of 30% + or -. |

There is a way to use SIPs to build a segmented circular house and not have any waste but the width of the SIPs will dictate the length of your wall segments. One would cut the SIP diagonally in half, then connect the two pieces back to back with a spline. This would give you a triangular section of roof with an eave edge that is 8' wide by however long the panel was. |

Here's a diagram. Would work for metal panels with a symetrical male/female lock like Structall's or PFF's. Won't work with a metal 'shiplap' male/female locking panel like Kingspan because when you flip the other half of the panel it reverses the lock and they won't mate.

Actually, you could still layout a roof with 'shiplap' locking metal panels, but you would have to cut up the panels in pairs and alternate the way you cut them, then swap out the halves so they will mate. Tricky. |
