The HotFlashing™ Raceway holds a single run of UL Listed self-regulating ice melt cable and spreads the heat up to 6 to 8 inches across the panel. Compared to a single run of exposed ice melt cable, the HotFlashing™ panel creates a much wider heated drain path that prevents ice melt water from re-freezing until it can be drained away from the structure’s foundation. In most cases a HotEdge™ Rail and heated gutters and downspouts are required for a complete system.
The HotFlashing™ Raceway can be used in the valley between roofs or next to the vertical walls of dormers or second stories. The Raceway hides the ice melt cable and is available in a number of different colors to match the roof covering. This presents a clean and attractive street view.
The partial exposure of the ice melt cable provides for insertion, inspection and replacement of the cable in compliance with the NEC (National Electrical Code) requirements.
Flat Flashing: This profile is commonly used in the valley intersection of two adjoining roof surfaces. They can be slide under the existing shingles and secured with nails or screws that are sealed with roofers sealing compound. The panels can be bent or trimmed at the time of installation to clear existing nails or other obstructions. For roofing material that cannot be penetrated, special glue, available from the factory, is used to secure the panels. If the existing valleys have a “W” flashing in place, two runs of the panels are recommended. A maximum horizontal melt path of 6 to 8 inches from the ice melt cable can be expected.
Right Angle Vertical Flashings: These right angle flashings are used to create a melt path next to vertical walls, skylights, dormers, chimneys or other types of protrusions from the main roof surface. These areas can trap ice and snow and create hidden ice dams that need a drain path.
The panels are available in 3, 6, 10 and 14 inch widths. For example, using a 10 inch total width, the vertical 90° flange bend is available at 4 inches to create a 6 inch vertical flange or at 6 inches to create a 4 inch vertical flange. Please note the total width measurement includes the horizontal and the vertical lengths.
