Using subflooring in a building offers several essential advantages, with the primary benefit being that it provides a supportive layer under finished floors. This support layer is crucial as it helps to distribute weight evenly across the floor joists, leading to increased structural integrity and stability within the building. By creating a solid base, subflooring helps to reduce the likelihood of sagging or bouncing in the finished flooring above, which can enhance the overall comfort and usability of the space.

Moreover, subflooring is instrumental in reducing noise and providing insulation, contributing to a more pleasant living environment. It also acts as a barrier that can help to reduce drafts and moisture intrusion, further protecting the integrity of the finished flooring material above.

In essence, the support that subflooring provides is fundamental to the proper function and longevity of flooring systems, making it a critical component in building construction.
