What must you do when sealing a window with Silas Kraft paper?

When sealing a window with Silas Kraft paper, the proper action is to cover the metal flanges. This is essential because the metal flanges are designed to provide a secure attachment point for the window and help prevent water infiltration. By covering them with Silas Kraft paper, you create a moisture barrier that protects the integrity of the window installation. This approach helps prevent issues such as leaks and mold growth, ensuring a more durable and reliable seal.

Proper installation requires careful attention to the flanges as they are a critical point where water can penetrate if not adequately sealed. In this context, the use of Silas Kraft paper is critical for effective waterproofing, emphasizing the importance of covering the flanges specifically to guard against potential water intrusion.
