The Insulspan Structural Insulating Panel (SIP) System consists of a solid,
one-piece, pre-cut SIP units that are ready to install as wall components
suitable for many residential or commercial building applications.
Insulspan SIP wall assemblies contain less dimensional lumber. In
wood-framed construction a thermal bridging is created between the
exterior of the building and the finished interior when insulation is
interrupted by wood studs which also leave more than 20% of the wall area
uninsulated. Insulspan SIP wall assemblies provide higher R-values than
typical wood-framed construction alternates as there are significantly fewer
Higher R-value keeps conditioned air in. The R-value of a wall is a measure
of its ability to keep heat from flowing through it. Higher R-value for walls
means less heat loss and less energy needed for heating and cooling.
The Insulspan closed cavity wall and roof design prevents air movement.
In wood-framed construction, wall R-value is decreased by insulation gaps
around wood framing and by settling of insulation. These defects increase air
leakage through the construction. This not only increases energy use, but
can lead to condensation on the surfaces of wood components within
assemblies. The continuous core of EPS insulation in an Insulspan SIP vastly
reduces air leakage and heat loss, while also allowing better control of indoor
