I am curious if anyone is familiar with or has insight related to Tremco Alumanation 301. A company is asking to install this on the existing roof. I believe this product does not have a fire rating. Nothing related to the structure is changing just adding the coating. Curious if you would allow this to be used. Any thoughts would be appreciated.
