Timber frame construction has become one of the fastest-growing building methods across residential, commercial, and modular projects. Speed of construction, sustainability, and design flexibility are driving its adoption. At the heart of a well-performing timber frame building lies one critical component: the exterior sheathing board.
Speed is one of the main reasons prefabricated construction has gained momentum across residential, commercial, and modular building projects. Factory-controlled production, reduced site labor, and shorter build programs allow developers to deliver projects faster and more cost-effectively.
Selecting the correct exterior sheathing board thickness is a critical decision in any building project. Thickness directly affects structural stability, airtightness, fire performance, durability, and long-term energy efficiency. Choosing the wrong thickness can lead to performance gaps, higher maintenance costs, or compliance issues.
Airtightness has become one of the most critical performance requirements in modern buildings. As energy costs rise and regulations tighten, uncontrolled air leakage is no longer acceptable in residential, commercial, or industrial construction.
Exterior sheathing boards play a central role in improving airtightness and energy efficiency by forming a continuous,
