Which of the following are functions of wall sheathing?

Wall sheathing plays a crucial role in the structural integrity and overall performance of a building. Its primary functions include strengthening and bracing the wall structure, adding rigidity, and acting as a seal for the house.

When wall sheathing is installed, it helps to distribute loads more evenly across the framing of the wall, thus increasing the overall strength of the building. This added strength is essential to resist lateral forces such as wind and seismic activity, ensuring that the structural integrity of the home is maintained.

In addition to providing strength, wall sheathing also contributes to the rigidity of the walls. This rigidity helps prevent bowing or warping over time, which can be caused by various factors including changes in temperature and humidity. By reinforcing the structure in this way, wall sheathing contributes to a more durable and stable building.

Moreover, wall sheathing acts as a barrier that helps seal the house from air and moisture infiltration, which can lead to energy inefficiencies and potential damage to the building materials over time. By controlling air leaks, the sheathing can improve the energy efficiency of the home and contribute to better indoor air quality.

These multifaceted functions make wall sheathing an essential component in residential construction, contributing to both the strength and performance of the building.
