Wall Sheeting is the unsung hero of sturdy, energy-efficient buildings. This flat layer, installed before a building’s siding is applied, protects against external elements like wind and moisture and distributes structural loads evenly across the framing. It’s especially important in climates like Northeast Wisconsin where heavy rain and snow are common. Without a strong, well-installed layer of sheathing, even the best siding materials can fail long before their time.
Sheathing is typically made from wood panels or boards that builders install over a building’s framing, creating a stable base for roofing and siding materials to be attached. Sheathing is available in a wide range of options, with each type serving a unique purpose. The type of sheathing chosen will depend on a number of factors including budget, climate and installation method.
Among the most common sheathing materials are Oriented Strand Board (OSB) and plywood. OSB sheathing is often used for residential and commercial construction projects as it is cost-efficient and durable. It’s also lightweight and offers resistance to mold, fire, and insects. It is recommended to use a weather barrier over OSB sheathing, as this will help prevent moisture infiltration.
Glass mat sheathing is another popular option, as it offers a combination of strength and moisture-resistance. It is designed to withstand the harshest weather conditions, while remaining affordable and easy to install. While it is a great choice for exterior walls, it should be properly inspected and maintained to prevent the formation of water spots or rot.
Cement board sheathing is a more expensive option, but it is also extremely durable and moisture-resistant. It is typically used for commercial buildings and can be found on high-rises, as it offers a solid foundation for tiles or other masonry products. It is also a good choice for seismic areas and high-rises.
Plywood sheathing is a cost-effective material that is resistant to mold, insects and moisture. It is also an excellent choice for cold climates as it has a higher R-value than other sheathing types, allowing it to effectively insulate homes and reduce energy bills. Sheathing that is glued together with wood veneers is usually not recommended for exterior applications, as it may be susceptible to damage from wind or ice.
Whether choosing gypsum sheathing, glass mat sheathing, OSB sheathing or plywood sheathing, it is important to choose the right option for your project. The proper sheathing will help ensure that your siding looks beautiful and performs well for decades to come.
