Modular construction, which is what Pro-Fab does, makes it possible to build practically the entire home in the factory, in the form of modules. For example, a bungalow usually consists of two modules, while a cottage has four. The level of finishing on the modules is very high and may include all doors and windows, the interior divisions, insulation, cabinetry, the bath and shower, and much of the plumbing and electricity. When the modules are installed on the foundation, the project is already at a very advanced stage.
Panelized construction makes it possible to build walls with the insulation already installed. When the walls are delivered to the worksite, they must be assembled to start construction. Pro-Fab does not offer this option.
