What type of construction is assembled on site, made of foam insulation sandwiched between sheets of plywood?

Panelized homes are constructed using panels that are assembled on site. These panels typically consist of foam insulation sandwiched between sheets of plywood, which provides both structural integrity and thermal insulation. This method of construction allows for quicker assembly and can contribute to energy efficiency due to the insulation properties of the foam.

The process of creating panelized homes often involves prefabrication of the wall panels in a controlled environment, followed by transportation to the building site where they are assembled. This technique can also lead to reduced waste and shorter construction times.

In contrast, safe homes refer to structures built to withstand various environmental factors but do not specifically describe the construction method involving insulated panels. Type 4 and Type 5 constructions describe buildings made from heavier timber and light-frame wood, respectively, and are not characterized by the use of foam insulation and plywood assembly.
