window flashing

Window flashing is a thin, weather-resistant barrier installed around the edges of a window opening to prevent water infiltration. Its primary purpose is to direct rainwater and moisture away from the wall opening, ensuring it does not seep into the building structure. Proper flashing helps maintain the integrity of the building by preventing water damage, mold, and rot. It is typically made of materials like metal, plastic, or waterproof membranes, and is carefully installed to create a continuous, secure seal between the window frame and the surrounding wall.
