Examples of modular components: 1) Studs (veritcal members in walls) and joists (horizontal members supporting floors) are standardized to be placed 16 (40 cm) and 24 (60 cm) apart. 2) Batt insulation (fibreglass rolls) is also standardized to 16 ( 40 cm) and 24(60 cm) width, to fit between studs. 3) Plywood sheathing. Gyprock (drywall), and composite board are standardized to 4 width in general which fits into the regular spacing of studs and joists. Floor framing Once the foundation is finished, a platform is constructed which will support the walls surrounding the main floor, as well as supporting the decking of the main floor itself.
