Load Chart 8:
Allowable Header Loads (plf)
Condition 2–Panel is Not Continuous
Over Opening (Splines)
* indicates ultimate load divided by 3 for the design capacity.
In all cases where a concentrated load is placed over on opening or the design loads exceed the capacity of a
panel header, Premier Insul-Beam II should be used if possible or an engineered header assembly is required.
More information on this chart can be found in Technical Bulletin #10 (www.pbssips.com).
