Why is notching or drilling studs at the bottom becoming more popular?

Notching or drilling studs at the bottom is becoming more popular primarily because it facilitates the installation of insulation batts. This practice allows for better placement and fitting of structural batt insulation, ensuring that it fits snugly in wall cavities. Proper insulation is crucial for energy efficiency, as it helps to maintain temperature control within a space. By notching or drilling, installers can more easily maneuver the insulation into position, which ultimately improves the effectiveness of the insulation and the overall energy performance of the building.

While other options might seem relevant, they do not accurately reflect the primary advantage of this practice. For instance, reducing material costs, increasing load capacity, and simplifying wiring processes are not main reasons for the growing trend of notching or drilling at the bottom of studs. Instead, the focus remains on the practical benefits it offers during insulation installation.
