When strapping vertical siding, how should the straps be oriented?

When strapping vertical siding, the correct orientation involves using vertical straps on the wall with horizontal straps on the second. This method provides an effective support system for the siding installation, accommodating potential wall movement while ensuring that the siding can be secured correctly and allows for proper drainage and moisture control. The vertical straps create a direct connection for the siding panels, enhancing their stability.

Using horizontal straps on the second level offers additional support and aids in the alignment of the siding, helping to maintain a uniform appearance and structure across different elevations. This combination optimizes the structural integrity of the siding installation and reduces the risk of issues such as warping or buckling.

In this context, other combinations of strap orientations may not provide the same level of effectiveness in supporting the vertical siding or might complicate installation processes, potentially leading to problems in both aesthetic and functional aspects of the siding system. Thus, employing vertical straps on the primary wall surface with horizontal straps on the upper levels is the preferred practice for achieving a robust and reliable vertical siding installation.
