I am considering building a 2200 sq foot two story SIP home in SE Oklahoma. Can anyone give recommendations for a SIP company in OK or north Texas? I'm looking at having the SIP shell erected on my slab and taking the construction over from there.

If you get precut walls, you can probably do the project yourself. Korwall is in Dallas and Chapman Building is in Kerrville north of San Antonio. If you need a complete engineered system of floors, walls and roof or would like someone to come manage a couple days of the SIP erection, I might be able to help.

Yes there is a company here in ok that you can get panel from they make a real got panel email me at [email protected] and I will get you the information.

I'm in the DFW area and have been working with SIPs for over 12 years.
Both SIPs Texas and EH Systems are good guys to work with. 
Where at in OK are you building?  I do travel a bit to install SIPs, and you project sounds like one I'd be interested in.

I'll put you in touch with the guys you need to talk to to get the best deal on panels.
