Beginning in 1995 and continuing through 1997, 319 homeowners invested in the Crown Hills Subdivision east of San Diego built by
RJT Builders LLC. of Phoenix, Arizona. RJT was the first large scale developer to step out on the cutting edge of building technology and
utilize structural insulated panels for the exterior walls in a production build of this size.

The heating and cooling costs for Crown Hills have been constantly monitored by RJT and compared with comparable sized homes
in the same geographic area with data provided by San Diego Gas & Electric. Initially, the average energy bill for a home in Crown Hills was
$53.56 per month, while stick built houses of the same size were $125 to $135 per month. In June of this year Californians experienced
the beginning of well publicized rate hikes that caused the cost of energy, initially in the San Diego area and now throughout California, to
skyrocket an astounding 300% due to deregulation.

Assuming energy costs stay constant for the next 7 years, (which is not likely!) a Crown Hills investor will have realized a gain in
10 years of over $22,000 compared to his neighbor living in a stick built house.

If this does not convince you to use SIP’s in your next project consider these other facts about panel construction!

* STRENGTH – Because of the monolithic nature of panel construction, your houses will be up to 3 times stronger than
conventionally framed houses.

* QUALITY – Panels assure you of straight flat walls, NO FRAMING CALLBACKS for inferior lumber problems, warped studs, nail
popping, or drywall cracking.

* SPEED OF CONSTRUCTION – Through proper design and utilization of entire building system, significant labor costs and
construction loan interest savings can be realized.
