We are adopting the 2009 energy codes which will require insulated headers. Does anyone have some good examples of these? Im thinking 2- 2Xs with foam board sandwiched between or a another code compliant method for this. Thanks in advance.

Where is the header insulation required in the 2009 IECC?

they are not required to be what Mark posted.steveray said:
Table 402.4 requires headers to be insulated. It does not tell you what kind of insulation.

That is kind of funny, especially because you can't do insulatable corners with BW panels...Unless you are using foam during framing or you don't mind sealing wet fiberglass in your walls....No "open" corners R602.10.4.4(1)

Exception: The first braced wall panel shall be permitted to begin 12.5 feet (3810 mm) from each end of the braced wall line in Seismic Design Categories A, B and C and 8 feet (2438 mm) in Seismic Design Categories D0, D1 and D2 provided one of the following is satisfied:
1. A minimum 24 inch (610 mm) long, full-height wood structural panel is provided at both sides of a corner constructed in accordance with Figure R602.10.4.4(1) at the braced wall line ends in accordance with Figure R602.10.4.4(4), or
2. The braced wall panel closest to the corner shall have a hold-down device with a minimum uplift design value of 800 pounds (3560 N) fastened to the stud at the edge of the braced wall panel closest to the corner and to the foundation or framing below in accordance with Figure R602.10.4.4(5).
#2 is what we typically see to allow the open corners and be able to insulate after the house is dried in

Typically we end up with panel to panel, guys around here don't want to mess with any more straps...I guess I should have said that open corners are more the exception than the norm now....I don't feel old enough to have seen 3 stud corners go to 2 stud corners and now back to 3...

I believe the 2012 changes the corner requirements and a strap will be required.

Never noticed that...kinda dumb that they call out specifics and then send you back to general...But what about when they compress the insulation in those spots to clear the backing stud?...... KIDDING!
