Description

Metal back channel flashings help to prevent rain, dust, pests, and wind from entering where your polycarbonate roof butts into fascias and walls. It does a similar job to an apron flashing.

Specifications:

• 3.6m length
• Grey Friars or Titania (white) colour
• Includes 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.
