aluminum foil butyl rubber tape

Can aluminum foil butyl rubber tape be used as a permanent application ? The data sheet on this stuff does say it can be used for patch work. I have always seen aluminum flashing used around chimneys. I wanted to get everyone’s opinion before I finished my report. Thanks In Advance

It is the next best thing.

Looks like a temporary (Patch) fix to me. Tape is not flashing IMO.

Looks like it’s already coming apart.

Why is flashing and stairs so hard for people to grasp?

None of the modified membrane stick-back flashing tapes are designed for direct exposure. The reflective tape is primarily for heat reflection and not weather proofing.
Installing it over block or brick or anything that is subject to moisture intrusion would definitely take it off the list. It’s an improper installation and clearly temporary at best.
