Securing Vinyl J-Channel to Foil Covered Foam Board w/Butyl Tape


#1

Tape would be either Window and Door Sealing Tape or Flashing Tape (or a glossy white surfaced tape that is used on gutters.)

Reason why is I don’t want to run nails through step flashing for two reasons: 1) flashing is 24ga galvanized and holes would have to be drilled and 2) I nail flashing to the roof, not he wall so future flashing replacement does not required removing dormer siding.

My concern is that this tape may come loose in 10-20 years.

You need to have a mechanical attachment, the foil will peel off the foam if you try to use glue or tape.


#3

Tape will not hold. If you don’t want to nail through steps use long zips into steps.


#4

Yeah, I was thinking tape was not the way to go.

I ended up making 24ga galv “J” hangers I crimped through the nail slots. Had to punch hole for nail but no biggie.

What are “long zips?”

Zip screws…
