What Kind of Sheathing for Exterior Walls?

Introduction

Sheathing, also known as wall sheathing or wallboard, is a crucial layer in exterior wall construction. It performs numerous essential functions, including providing structural support, bracing the wall against wind loads, and acting as a moisture barrier. Choosing the right type of sheathing is vital for ensuring a durable and weather-resistant exterior wall.

Types of Sheathing

There are several types of sheathing materials available, each with its own advantages and disadvantages. The most common types include:

Oriented strand board (OSB): OSB is a type of engineered wood made from thin strands of wood glued together. It is strong, durable, and relatively inexpensive.
Plywood: Plywood is another type of engineered wood made from thin layers of wood glued together. It is stronger and more moisture-resistant than OSB, but also more expensive.
Fiber cement board: Fiber cement board is a composite material made from cement, sand, and cellulose fibers. It is fire-resistant, moisture-resistant, and termite-resistant.
Glass mat sheathing: Glass mat sheathing is a type of sheathing made from fiberglass strands bonded together with resin. It is moisture-resistant, fire-resistant, and lightweight.

Factors to Consider When Choosing Sheathing

Several factors should be considered when choosing a type of sheathing for exterior walls. These include:

Climate: The climate in your area will have a significant impact on the type of sheathing you choose. If you live in a humid climate, you will need a moisture-resistant sheathing like fiber cement board or glass mat sheathing.
Wind loads: The wind loads in your area will also affect the type of sheathing you choose. If you live in an area with high wind loads, you will need a strong and durable sheathing like OSB or plywood.
Budget: The cost of sheathing can vary depending on the type and thickness. You should consider your budget when choosing a sheathing.

Conclusion

Choosing the right type of sheathing for exterior walls is essential for ensuring a durable and weather-resistant home. By considering the factors discussed above, you can select a sheathing that will meet your specific needs and budget.
