SIP (Structurally Integrated Panels) are a sandwich of OSB on top, 10 inches of styrofoam (R44) and tung and groove pine panels on the bottom.
Large, 4 foot wide panels are cut to fit on the ground, then lifted into place with a crane. Once in place they are secured with 13 inch screws into the structure (ridge beams, purlilns, etc.).
The installation should have taken 3 days, it took five (and way too much stress on my part).

First panel in place. A framer sits on the ridge beam to screw the panel into place. |

The steep 12/12 pitch of the roof makes it difficult to work on. Workers used toe boards to keep from sliding off. |

A panel flying into place. |

Another panel (attached to cable). On some afternoons, the wind picked up, making the panels higher to control. Good to say, no-one was hurt. |
