Long term thermal resistance values of the foam were determined in accordance with
ASTM C 1289-02. The R-Value of 0.55 for 7/16" OSB was obtained from ASHRAE
Handbook, Fundamentals.
For SI: Inch = 25.4mm; 1 pound per foot (ppf) = 14.59 N/m.
1 Prescriptive bracing requirements with Douglas Fir-Larch Framing under the 2009 IRC.
2 Not approved for use as prescriptive wall bracing where the design wind speed is greater than 110mph.
3 Engineered shear wall requirements with Douglas Fir-Larch Framing under the 2015, 2012, and 2009 IBC.
4 For framing with other than Douglas Fir-Larch, the shear value above must be multiplied by the Specic Gravity Adjustment Factor = [1 - (0.50 - SG)], where SG=Specic Gravity
of the framing lumber in accordance with the ANSI/AWC NDS. This adjustment factor must not be greater than 1.
5 Type R-3 R-sheathing panels have a foam plastic insulation thickness of .5". Type R-6 R-sheathing panels have a foam plastic insulation thickness of 1". R-9 R-sheathing
panels have a foam plastic insulation thickness of 1.5". Type R-12 R-sheathing panels have a foam plastic insulation thickness of 2".
6 Fasteners must be common nails or equivalent, or staples, of a type generally used to attach wood sheathing.
7 The shearwalls must have a maximum height-to-width aspect ratio of 2:1.
8 This panel and fastening conguration is only applicable to the prescriptive bracing requirements under the 2015 IRC.
