Structural Insulated Panels (SIP) are building
panels used in residential and commercial buildings that consist of
panels of insulated foam sandwiched between two structural facings. The
facings typically are (Oriented Strand Board) OSB. However plywood could
be used. These large panels are manufactured in a factory to exact
specifications and shipped to the building site where they are
assembled. SIPS construction is different than normal framing because
of the way the panels are constructed; they actually are the structure.
There are many differences. Foundation straps are used to secure the
panels instead of sill bolts. Panel corners and roof to wall
connections are screwed together. Special fasteners are used to attach
porch roofs to SIPS buildings. Floor joists are attached with a top
chord bearing hanger that is attached to the top of the SIPS panel. A
ridge beam and possibly a mid span beam may be used to support the roof
panels. Here is a video of a SIPS house being constructed: https://youtu.be/liTV_iLkdl0.

- Holes

center. No more than 2 horizontal chases shall be permitted in each wall
panel.
- The
walls are fastened to the foundation using approved fasteners
- Normally,
SIPS walls should be no taller than 10 feet
- SIPS

- Pressure
treated sill plates should be used and anchored to the foundation with
anchor bolts spaced a maximum of 6 feet on center. There shall be a
minimum of 2 bolts per plate section with one bolt located not more than
12 inches from the end of each plate
- Sill
bolts should be at least ½ inch in diameter and extend at least 7 inches
into the masonry. Nut and washers should be used.
