Cast Iron Counterflashing

Model Number:  1540 Series
The counterflashing is secured to the vent pipe by three vandal resistant screws. The top recess is partially filled with back-up filler, such as polyethylene foam or a dry, non-asphalytic material,such as oakum. It is then topped with epoxy compound (epoxy compound and partial filler not furnished).The joint between the flashing and the vent pipe is sealed and made watertight with epoxy compound and permits expansion and contraction of the vent pipe, or minor movement of the roof due to snow or rain loads, without disturbing the seal. The movement is not transmitted to the flashing and the vital bond between the flashing and the roofing felts is permanently protected.
