Some benefits of panelized homes are:

• a quick move-in date
• minimal warping caused by moisture
• cost savings through less waste

Homes may be selected from standard plans, customized or designed to fit an individual's needs. Optional features may be chosen, such as window systems, siding, shingles, whirlpool tubs and a wide variety of other components.

Panel basics: Some manufacturers sell just the shell which includes a complete set of wall panels, floor decks, roof, floor trusses, sheathing 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.
