Sheathing is the most critical “hidden” component of a business’s infrastructure because it provides the essential structural rigidity and a flat nailing surface for all exterior finishes. It acts as the building’s primary bracing against wind and seismic forces while serving as the secondary barrier for moisture and air infiltration when properly taped and sealed. For a business owner, high-quality sheathing is a vital long-term investment that prevents wall racking, enhances energy efficiency by reducing drafts, and ensures that expensive siding or masonry remains securely attached and level for decades.
