Headers are
generally designed at the time the panel layout drawings are made. Header
design load charts and other technical information can be obtained by
contacting (616) 399-1963. Refer to drawing
#38-501 and
#38-502 for
installation details for single and double plate headers. Field cut openings
may be made in wall panels as noted in drawing
#38-503.
Maximum
width for a field cut opening in a wall is 48". This width opening
assumes normal loading to the top of the panel. If an unusually high
point load is being carried by the panel above the opening the maximum
span may have to be reduced or a header installed. If there is a
question regarding the load carrying capacity of a field penetrated
panel, an engineering analysis should be conducted. Penetrations will be
necessary to install vent stacks, chimneys and other penetrations
through SIP roof panels. Small penetrations of 6" or less can be made
without 2x blocking, providing they are well sealed. See drawing
#38-505.
Insulate any voids between the object and EPS with foam.
