About ZINCALUME® Window Flashing

ZINCALUME® window flashing is a precision-engineered Z flashing designed to protect window openings from moisture, wind and water ingress. Made from genuine BlueScope ZINCALUME® steel, it combines strength, clean lines and corrosion resistance for long-term performance in Australian conditions.

Where It’s Used

This flashing is used at the head, sill and jamb of windows to create a watertight barrier between cladding and framing. It helps direct water away from the opening, protecting internal walls and insulation from leaks and rot.

✔ Available in standard Z profile or custom sizes to your specs
