The construction world underwent a remarkable evolution starting in the 1970s, fundamentally altering the way walls are framed. Long held as the gold standard, the 16-inch module was cherished. Nevertheless, the march of progress introduced an efficient and environmentally friendly alternative.
The transition from the 16-inch module to the 24-inch on-center stud spacing might raise questions about the structural integrity of buildings. After all, the 16-inch module had been a long-standing tradition. But when we delve into its history, we find that the 16-inch module was not the result of careful engineering but rather a practice dating back to England around 400 years ago. It was established as the maximum span to support wooden lath for plaster application. Fast forward to the modern era with the widespread use of drywall, and the game changed dramatically. The need for the 16-inch module diminished.
In addition to this shift, the building traditions of the past do not always align with contemporary needs. For example, if you were to break into the walls of an old house, you might be surprised to discover that the original builders did not use headers, yet the house still stands. This discovery leads modern engineers to question whether the traditional standards result in unnecessary waste. In fact, for every 20 houses built, the use of outdated techniques often results in the unnecessary waste of one house's worth of lumber.
Economy Starts with Intelligent Planning
Economical wall construction begins with intelligent planning. When working with a designer, the process begins by creating a framing elevation for each wall in your plan. This step involves studying the layout to eliminate excess studs, cripples, and headers. Sometimes, a simple repositioning of a window or door can make it align perfectly with the 24-inch modular layout.
While the transition to efficient framing techniques is a step in the right direction, some carpentry traditions are deeply ingrained and die hard. You might find carpenters adding extra studs at wall intersections, installing fire blocks where they're not needed, or even doubling up on trimmers at door and window openings. To make advanced framing work, close collaboration with your carpenters is essential. They need to understand the new system and the reasoning behind it.
Placing Structural Members Where They're Needed
The first rule of advanced framing is to place structural members where they're needed and omit them where they are not. To do this effectively, it's crucial to differentiate between load-bearing walls, which support the weight of the roof, floor joists, beams, and walls above, and non-load-bearing walls, which primarily support their own weight.
Not all exterior walls are load-bearing, but they must be able to resist the stresses of wind and seismic loads. When a wall is tasked with supporting both floor and roof loads, using 2x6 lumber at 24-inch on-center spacing is an efficient choice. This choice often proves to be more cost-effective than using 2x4 studs on 16-inch centers. Alternatively, you can employ 4-inch-wide engineered laminated strand lumber (LSL) studs designed to carry specific floor and roof loads at 24-inch spacing.
Meeting Building Codes and Beyond
While prescriptive building codes may not fully recognize the contribution of exterior sheathing and drywall, consulting a professional engineer to review your plans and determine whether your wall assembly meets the structural guidelines outlined in the code can provide peace of mind. Sometimes, the addition of structural sheathing can add enough value to justify using 2x4 studs, especially on the first floor of a two-story building.
In conclusion, advanced framing techniques and careful planning can lead to significant cost savings and reduced material waste in the construction of walls. These approaches not only make economic sense but also contribute to more efficient and sustainable building practices. They align with the changing needs and standards of modern construction, proving that building walls the new way is about optimizing both structure and resources to create better, more efficient homes.
In the construction industry, progress often comes from questioning the status quo and embracing change. Building walls, the new way is a testament to this progress, and it's a trend that's here to stay.
