In
the Fall of 1997, Habitat for Humanity built two similar single dwelling family
homes, one with SIP panels, and the other with stick fames. The SIP home located
in Sedro-Wooley, Washington contained 1,293 square feet and four bedrooms.
The 2x4 stick-built home located in Plains, Georgia consisted of 1,064 square
feet and four bedrooms. In a report summarizing the findings of the comparison
of labor man-hours between the two homes, Habitat for Humanity determined
that the "the SIP home saved 65% of the site labor when compared to the
stick-built home (1)."
The reason for this increase in construction efficiency is due to the fact
that SIP manufacturers - including Foam Laminates of Vermont - fabricate large
sections in their own facility, rather than have carpenters construct the
stick framing assembly on-site.
When building with SIPs, on-the site construction time is dramatically reduced
and this can have some considerable advantages to the homeowner. For instance,
a long fabrication cycle can limit access to construction labor and poor weather
conditions can hinder progress. In a time where labor can cost more than the
construction materials, perhaps the most alluring feature of SIP buildings
is that they can save labor and hence money.
One
of the best features of building with SIPs is there fast installation time.
Indeed, some analysis have shown that the construction time of a SIP building
can be shortened from four weeks to one week when compared to a similar stick
frame building. In fact, the Energy Studies in Building Laboratory at the
University of Oregon conducted extensive testing on the labor requirements
of SIPs and determined that SIP homes could be completed in 161 hours less
than their equivalent counterparts. This amounted to about 34% less on-site
construction time.
