Structural Insulated Panels (SIP) can create a strong, well-insulated, airtight, building envelope. They can, however, be unforgiving when it comes to moisture management. Most SIP dry slowly if or when they get wet, so back-vented claddings, robust flashing details, meticulous sealing of penetrations, and effective spot/whole house ventilation are all essential.

Detail Caption:

The drill bit must be long enough to penetrate up through the plates but not too long to fit in the rim joist area.
