[RE-wrenches] SIPs

[Dana]

We did a project with SIPs roof and the owner /builder  theoretically contacted SIPS and they had them cut out and lay in 2 x 10s as a backing with a bonding agent to the foam???? [Not known what this was]  and then high temp ice and water shield and then the synthetic recycled roof material.

 

Has anyone else heard of this procedure? 

 

If so do you know what the bonding agent would be?

Hi Luke Christy,
I am wiring a SIP house, and the plans called for hanging a fan on the ceiling.  I contacted the manufacturer and they suggested cutting out a rectangular section of the OSB board that extends well beyond the dimension of my ceiling mounted round metal box.  Then with a tool called a hot knife, the Styrofoam was melted away.  Next we gouged out more Styrofoam, several inches beyond the cut out and slipped some 2x wood blocks into the hole and screwed along the perimeter. Next screw the OSB cutout back in place, and now there is a large area to screw into for your mounting foot. I hope this makes sense.

Esteemed Wrenches,

 

We have a PV job in the works that will require mounting racking to several roofs that consist of asphalt shingles laid over SIP panels. The panels are standard 10" nominal thickness, with 9-1/4" of foam sandwiched by 1/2 OSB on each side. The rub is that the underside of the panels will be the finished ceiling (with 5/8" of wood over the OSB). 

 

I found a couple of threads in the archives discussing mounting to SIPs, but most comments suggest  through-bolting, and that is not an attractive option in this case due to the finished ceiling directly beneath.

 

The roofs in question are triangular in plan, and are fairly small (~ 15' x 15' x 21')

 

Does anyone have experience with mounting directly to the outer skin of a SIP panel? 

Suggestions on the best way to approach this problem would be appreciated. 

 

Thanks in advance.
