I am in the dreaming/scheming stages of my next construction project here in Maine.  I am very interested in SIPs and have a question for anyone who has gone that route.

Have you seen or heard of any applications that bypassed the interior drywall application all together?  I have a long standing bias against the stuff (waste, easily damaged, hard to find good installers/tapers/mudders, etc) and thought some type of spray finish inside could keep countless tons of it out of my next house.

Am I nuts for thinking along these lines? 

thanks in advance,

Even if you just texture the inside of the exterior walls, your interior partitions will still need the studs covered.
Drywall is still the most cost effective product. I would recommend sub-contracting the hanging and finishing out to one company to be responsible for the entire job and DO NOT pay in full until you are satisfied.

Thanks for the comments.  So, I surmise it is feasible for the interior facing SIPs, but the interior partitions pose a challenge. 

But, doesn't the function of the interior partition (from my non-architectual, non-builder point of view) change, given the SIPs exoskelton, from carrying any load to providing the following functions:

- privacy (sight)

- privacy (sound)

- hiding mechanicals (electric, plumbing)

So, I was thinking maybe conventional 2x4 interior partitions may be over engineered, not to mention relatively inflexible in terms of changing use/configuration of interior space over time. 

Could they be mini sandwiches, like SIPs, but not structural, with a thin skinned (Lauan-like equivalent) sheathing and a sound absorbing foam inside?   Or does covering up the foam with an inflexible material render it ineffective for absorbing sound?  Maybe a cloth wrapping, like office cubicle partitions? 

I certainly don't have all the answers, but I enjoy trying to dream up some possible solutions outside the mainstream accepted practice.  Glad to hear some of you are too.

thanks,
