What is Z Flashing and Why is it Essential for Windows?

Z flashing is a critical component used to direct water away from window openings, horizontal joints, and cladding transitions — helping to prevent water ingress and structural damage. Shaped like a “Z,” this flashing is placed above windows and between cladding layers to create a clean and effective seal.
