Panel basics: Some manufacturers sell just the shell which
includes a complete set of wall panels, floor decks, roof,
floor trusses, heathing and exterior doors and windows (sometimes
pre-hung). Others offer what is known as "full packages,"
or everything that's required to "turn key" or move
right into the home, even appliances.
Open wall or closed wall: Manufacturers offer open or closed
wall systems. In open wall systems the exterior sheathing
is applied in the factory to the stud wall, leaving a totally
open interior wall partition for inspection by local code
officials. Insulation, wiring, plumbing and drywall all are
added at the job site.
In the closed wall system, the entire wall is made and it
includes the electrical and plumbing installed, with inspections
being performed at the factory by code officials or third-party
agents. In the field the panels need only be erected and the
inter-panel connections completed.
Panels can also be constructed of Structural Insulated Panels
(SIPs) made in factory by sandwiching an expanded polystyrene
insulation core between two sheets of oriented strand board
(OSB) to achieve a durable, low-cost, energy-efficient product.
Studies have proven that using SIPs for the exterior provides
substantial energy advantages compared to ordinary wood-framed
walls with fiberglass insulation. Replacing conventionally-framed
walls with SIPs may increase production costs minimally, but
result in lower energy bills.
Panelized homes certified by EPA's and DOE's Energy Star Homes
program may ease homebuyer loan qualification and interest
rates. Certification may also add value to the home.
Geodisic dome homes are constructed of trianular panels, creating
an energy efficient home that maximizes living space using
a minimal amount of materials.

According to a recent study by The Freedonia Group, a Cleveland-based industrial market research firm, the amount of factory- or systems-built housing will grow 1.2% annually through 2005.
Modular homes account for one of every 10 homes built in the Northeast, according to the NAHB’s Building Systems Council. That region ac-counted for 29% of the nation’s modular activity. The South Atlantic region was a close second with 26%, and the Great Lakes region ranked third at 24%.
The most popular states for modular construction were North Carolina, Michigan and New York.
A good many of the homes you see today — perhaps some of your competitors’ — are modular homes. In 2001, modular homes accounted for 3% of all single-family homes constructed, the BSC says. Outside of metropolitan areas, that figure jumped to 11%.
