NOTES:
-
2X Top Plate joints must be staggered
a minimum of 1' from panel joints.
-
For non-load bearing walls, refer to
Transverse Load Design Charts #1, #3 and #3a for transverse capacity.
-
Minimum edge bearing for roof, floor
or ceiling panels is 1 1/2".
-
For application of Structural
Insulated Panels as flooring, a minimum of 7/16" OSB or equivalent is
required to provide additional impact and point loading resistance.
-
For sloped panels, the loading
conditions and panel capacities should be reviewed based upon the
inclined panel length.
-
SIPs should be designed to comply with
the deflection limits of the applicable building code.
-
SIP Load Design Charts are for total
load (dead load + Live Load). For long term deflection under
sustained load (creep), additional deflection must be evaluated.
