I'm building a small cottage (28' x 24') trying to be as "green" as possible, on a tight budget. The contractors will be doing the work, and I'm trying to do as much reasearch as possible going into the project. I'm using SIPs on the walls and roof, with plaster on the walls (hopefully). For the  ceiling, it looks like gyp board attached to the underside of the SIPs.  When trying to research this, most of the info on joint compound/mud indicates that it is made out of vinyl.  Are there alternatives to this, stuff we could use on the drywall that doesn't have vinyl in it?  I spent some time searching the site and couldn't find any topics on this. I apologize in advance if I missed something obvious.

Thanks for any info,
Regina

Regina,
There is one product on the market that holds some interest as a joint compound replacement.
It is called RapidSet OnePass and is made by CTS Cement Manufacturing Corp. It is a cement based product that is waterproof when dry and supports no mold growth. Check it out at www.ctscement.com.

Wes,

This looks great. Thank you so much.
