	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.
