Subflooring forms a large platform that covers the entire width and length of a house, providing the necessary base on which to secure the walls. This program explains how to frame the floor of a new home using the platform framing method. Along with safety, tool, and green-building tips, students learn the basics of placing and anchoring sills, butting and splicing, installing beams and joists, spacing, bridging, and laying both tongue-and-groove and square-edge subflooring.
