The sheathing installation is a crucial step in the construction process, providing structural stability and acting as a base for other materials like siding. The installation of structural exterior wall sheathing typically occurs after the walls of a structure are framed, secured, plumbed, and braced. The sheathing ties the framing studs together, making the walls resistant to twisting and bending, and provides a protective barrier against external elements like rain, snow, and wind.

Different types of sheathing materials can be used, including wood-based structural sheathing (like plywood and oriented strand board), gypsum-based structural sheathing, glass mat sheathing, cement board structural sheathing, and specialty sheathing like Barricade Thermo-Brace®. Each type of sheathing material has its own specific properties and applications, such as improving energy efficiency, providing fire resistance, or reducing sound transmission.

The installation process involves several steps, including selecting the appropriate sheathing material, calculating the quantity needed, placing, securing, and potentially cutting holes for windows and doors. It’s vital to ensure that the sheathing is installed accurately, with the edges lining up perfectly with the outer wall and other ends of the sheet on the center of a stud, to provide the necessary structural support and protection.
