| I read something on a web site within the past two weeks about a lawsuit in Alaska concerning houses built with SIP panels which are now leaking, etc. Unfortunately I didn't capture the article and now find I need it. Please advise. Thks! |

| The OSB , Sips story in Alaska is old news several years back ... attributed to improper installation |

| Appreciate you letting me know. I'm a relative newcomer to this technology. |

WOW....
I remember this story,
I heard that during the inspection they found cases of unused mastic, and panel splines used instead of solid members for the roof.
Panels are great, but not magic. lol
improper installation pretty much sums it up... |

Only a problem if the snow load is 200lb/ft and the span between supports exceeds that of the manufacturers testing data.
Before you spec a product for your application, research it and understand its capabilities.
If a SIP manufacturer's testing data shows that an 8" roof panel with panel spline connections mathematically will work for a roof load of 40psf and the span is borderline for that value, don’t roll with it to save a couple of bucks. Understand, you are choosing a premium product for your application and use something that wont deflect over a duration.
Personally, I even frown on double lumber connections. If you cant use I-joists, or have to use (2)2x's as a spline, maybe substitute for an alternate engineered lumber. This will not only provide for an easier installation (as engineered lumber dimensions are typically more true) it will also eliminate any seams. I’ve heard stories of 'being able to view light' through double lumber splines, even when following manufacturer guidelines for mastic application.
Where are you building?
What is the engineering data for your site?
Spans? Loads? |

In any event, the house is done, so I guess I will see over time.
