5. Thermal Barriers: Interior surfaces of SIPs shall be finished with a
minimum of 15-minute thermal barriers, such as gypsum wallboard,
nominal 1” (25mm) wood paneling, or other approved materials. Apply
code approved thermal barriers according to SIP manufacturer’s
6. Restrictions: Do not install SIPs directly onto concrete. Do not put
plumbing in SIPs without consulting SIP manufacturer. Do not over cut
skins for field-cut openings and do not cut skins for electric chases. SIPs
shall be protected from exposure to solvents and their vapors that
damage the EPS foam core.
