Colorbond Apron Flashing Trimdek
This Colorbond apron flashing is shaped to suit Trimdek sheet profiles, sealing the roof-to-wall junction where the sheet meets a wall. The apron is profiled so it sits over the Trimdek ribs and carries water away from the wall face, instead of bridging over the profile and leaving a gap. It is made from 0.55mm BMT Colorbond steel, cut to length with a +200mm / -0mm tolerance, and sold per lineal metre.

Installation
Fix the apron so the vertical leg runs up the wall and the profiled leg runs over the Trimdek sheet. The profile sits down over the ribs, so the flashing follows the sheet shape instead of bridging it. Fix the wall leg into the mortar joint or wall, seal the top edge, and fix the roof leg into the sheet to finish the junction.
Applications
- Roof-to-wall junctions on Trimdek sheet roofs

Frequently Asked Questions
Why does Trimdek need its own apron flashing?
Trimdek is a ribbed sheet profile, so a flat apron would bridge over the ribs and leave gaps. The Trimdek apron is profiled to sit down over the ribs and seal the junction properly.
What roof profiles does it suit?
It suits Trimdek and similar ribbed sheet profiles. If your roof is corrugated or Klip Lok, choose the apron shaped for that profile instead.
How is it priced?
It is priced per lineal metre including GST and cut to your required length with a tolerance of +200mm / -0mm.
Can I get it in Zincalume?
Yes. The same Trimdek apron flashing is available in Zincalume for an unpainted finish.
