Panel A is made of two equal layers of 7/16" APA rated (24/16) OSB.

Panel C is made of a layer of 7/16" OSB APA rated (24/16) and a layer of 19/32" plywood.

Each skin is rated (24/16). Each type has a core of 0.95 pcf minimum density EPS foam adhered to the sheathing with glue and set under pressure.

Notes:
1. Values shown are allowable loads for the shown spans (DL + LL).
2. Table reflects two deflection criteria, the L / 360 values should be used if the
header will be support for floor loadings.
3. These headers must have a dimensional lumber single plate at top and bottom
and along both end edges.
4. All values shown are for normal duration loads. No increases shall be allowed.
5. All values listed are for single spans supported at each end.
6. Since the bottom plate will be used for transfer of the transverse loadings the
following loads cannot be exceeded or a double plate will be required:

4' = 222.8 plf     6' = 99.02 plf     8' = 55.70 plf     10' = 35.65 plf     12' = 24.76 pl
