Z Window Flashing 100 x 40 x 10

The Z window flashing is a 100 x 40 x 10mm profile that seals the head and sill of a window opening, protecting the home from water leaks. The deeper 40mm leg gives more cover at the sill, where a wider flashing is needed to shed water away from the frame. It is available in Colorbond or Zincalume, cut to length with a +200mm / -0mm tolerance, and sold per lineal metre with GST included.

Installation

Fit the Z flashing over the top of the window frame so the top leg sits behind the cladding and the lower leg sheds water over the frame. At the sill, the deeper 40mm leg runs under the window and directs water well clear of the frame. Fix it through the legs into the frame and seal the ends, and lap the lengths at the joins for a continuous line.

Frequently Asked Questions

What is the difference between the two Z flashing sizes?

The 100 x 40 x 10 has a deeper 40mm leg than the 100 x 15 x 10, which gives more cover at the window sill where water needs to be shed further from the frame.

What is a Z window flashing for?

It is a barrier flashing fitted over the top of a window frame and at the sill, directing water away from the opening so it cannot leak into the wall cavity.

How is it priced?

It is priced per lineal metre including GST and cut to your required length with a tolerance of +200mm / -0mm.

Which finish should I choose?

Choose Colorbond to match the cladding, or Zincalume for an unpainted aluminium-zinc finish.
