What is the minimum distance required between joists for proper installation?

The minimum distance of 16 inches between joists is a standard practice in construction that ensures proper structural support and stability for flooring systems. This spacing allows for adequate weight distribution and helps to prevent sagging or deflection in the floor, which is crucial for safety and durability. Additionally, this spacing is compatible with standard sheet goods, like plywood and oriented strand board, which are typically manufactured in 4-foot widths. By having joists set at 16 inches apart, builders can easily install these materials without needing to cut them down, promoting efficiency and maintaining the integrity of the floor system. This spacing also accommodates insulation and other installations, contributing to energy efficiency in buildings.
