How We Build

Easy to Use - Structural Insulated Panels, SIPs ~ Interesting Facts

The use of SIPs in residential and commercial construction in the U.S. has more than doubled over the past 4 years, with a 34% increase in 2001, and preliminary figures indicate about a 50% increase in 2002.  It is  anticipated that THE USE OF SIPS WILL EXPLODE IN CALIFORNIA IN 2003 with  continued dramatic increases over the next few years, primarily due to rising energy costs.  In order to reduce the volume of energy required to heat and cool homes, and commercial buildings, the California Energy Commission is currently in the process of revising the energy code (Title 24).  The Commission has targeted July 1, 2003, for adoption of these updated standards, which are planned to go into effect in conjunction with the California building Code, and will likely be mandatory by 2005. The emphasis will be on better insulated, tightly constructed, more energy efficient buildings.  SIPs already not only meet, but exceed these new stringent standards.

Another major reason for this expanded interest in SIPs is the poor quality of lumber available for residential construction in the U.S.  Most framing lumber is green, typically with a moisture content of about 35%, and quite often has other defects such as excessive knots, �wane�, mold, etc.  Use of this poor quality material for the primary structure of a building can result in many serious problems, ie: uneven walls and ceiling surfaces nail or screw �pops� in drywall, toxic mold (known as black mold), etc.  The demand for more healthy and energy efficient homes is so strong that many high volume home builders have started using SIPs. 

HERE�S THE SUMMARY�

�The advantages of building with SIPs compared to conventional framing and insulation��

• Much more energy efficient. U.S. Dept. of Energy: �Definitive accredited testing proves that SIPs out perform conventional frame construction by at least 66%�

• Substantially reduced energy bills for the life of the structure.

• May use smaller HVAC system.

• Will meet the new title 24 requirements, scheduled for adoption by 7-1-03.

• At least 2 � times stronger (proven in earthquakes and hurricanes).

• Much quieter interior environment.

• Less jobsite waste.

• Close-in the building in approximately 1/3 the time.

• Walls are straight, square and plumb.

• No sub-standard lumber to cull out and throw away.

• Easier, faster, and less waste during drywall installation (no nail or screw pops).

• Easier installation of cabinets, fixtures, trim etc. hang pictures, shelves, etc. any where!

• No irritating fiberglass insulation.

• Very little chance of toxic mold inside walls.

• An environmentally responsible choice, not only due to the conservation of energy, but the system requires up to 75% less dimensional lumber.
