Install Upper Level Subflooring

What happens here

Following the window installation, the focus shifts to the upper level of the shed, where workers are installing the subflooring. This involves laying large sheets of plywood or Oriented Strand Board (OSB) onto the floor joists. The process typically starts by measuring the area and cutting the subfloor panels to the required dimensions using a circular saw. Construction adhesive is often applied to the top of the floor joists before the panels are laid down; this helps bond the subfloor to the joists, reducing squeaks and increasing the floor's rigidity. Once positioned, the panels are then securely fastened to the joists using subfloor screws or nails, driven in with a drill/impact driver or nail gun, respectively. Workers ensure adequate spacing between panels for expansion and contraction. The completed subfloor provides a stable and level base for any subsequent finished flooring materials.

Goal: Create a stable and level subfloor on the upper level of the shed.
