A panelized home is a pre-engineered structure. The theory behind this type of construction is that, as most parts of the building are pre-built in a controlled environment, the craftspeople will not be effected by weather, lack of materials at hand, unexpected cost increases for building materials, or other obstacles that arise whenever one is building a house on site.
Panelized homes should not be confused with modular or manufactured homes. Panelization is best understood as one step above stick framing. When stick framing, the contractor has an assortment of lifts of wood delivered to the site. The crew then takes the studs and cuts and assembles pieces into 'panels' which are then tilted up into place and fastened down.
What is included? All framing components including: floor system, roof trusses, wall panels, complete with framed openings for windows and doors; sheathing (factory applied on exterior walls), roof finish: shingles, felt ice and water sheild; vinyl siding, soffit and fascia; windows and doors; insulation, poly and caulking; gyprock (sheet rock) and accessories; baseboard, casing, closet shelving, door hardware, etc. Panelized homes are classified as a stick-framed home and can therefore be built in most of the same locations.
