Prior to installing vertical vinyl siding, it is crucial to install vertical strapping at a spacing of 600 mm (24") on center. This step is important because vertical strapping provides a solid and stable framework to which the siding can be securely attached. It helps to create a flat, even surface, which is essential for the proper installation of vinyl siding. This ensures that the siding panels have the necessary support and alignment, preventing issues such as sagging or warping over time.

Moreover, the vertical strapping allows for more effective drainage and ventilation behind the siding, which is vital for the longevity of the material and to help reduce the risk of moisture buildup that could lead to mold or rot. Properly installed vertical strapping also accommodates the expansion and contraction of vinyl siding due to temperature changes, thus enhancing the durability of the installation.

In contrast, other choices either specify different configurations or incorrect orientations for strapping that do not meet the installation requirements for vertical siding.
