My interior walls are sips panels with drywall and plaster. Any suggestions as to what the best method of mounting shelf brackets to the walls? I'm a bit worried that if I use long screws to mount the brackets, they might pull out if they don't reach into the OSB board. Any suggestions?

Huggie, Try using 'Molly' type bolts. You can buy them in various sizes. I have heard of people using them for heavy Kitchen cabinets, so they can support quite a bit.

....jc If you're not building with OSB SIPS(or ICF's), why are you building?

I saw these on HGTV when featuring the 2006 Hardware show. Worth a look http://www.raptoranchors.com/index.html

Are there studs between the SIP and the drywall? If so, mollies or any anchor designed for drywall should be fine. If the drywall is mounted to the SIP or if it's the inside face of the SIP you have more to contend with. If the drywall is mounted on an OSB faced SIP with no space between them I'd probably use screws that are long enough to just penetrate the OSB without going much deeper, since the foam is not something you can anchor into, anyway. If the drywall is the inner side of the SIP, I wouldn't want to mount anything substantial to it– I'd consider framing out that section of wall and mounting drywall to put mollies into. What kind of weight are the shelves going to hold? A few nick-nacks shouldn't be a problem, but a set of encyclopedias might tear the brackets off the wall.
