Colorsteel metal back channel flashings help to prevent rain, dust, pests, and wind from entering where your polycarbonate roof butts into fascias and walls, or where it sits under a gutter. It does a similar job to an apron flashing.
- 3.6m length
- Grey Friars or Titania (white) colour
- Includes soft foam insert
- U shape for corrugated or Greca (45mm x 20mm x 20mm)
- U shape for 5-Rib or Custom Glaze (45mm x 35mm x 35mm)
Note: Soft foam insert is not completely waterproof, but will stop dust, debris and a certain amount of water. If you want something completely watertight then you can also add foam infill (closed-cell foam) into the back channel.
