RE: Silverstein Project
Dear Sean,
I have reviewed the roof assembly below (MM6125-FR, Hydroflex 30 and Hydroguard) for
the Silverstein project, the assembly meets the UL Class A system 3 (Deck: C-15/32). The use
of the “Styrofoam panels surfaced with 3/8-inch concrete motor” is not listed under this system
in the UL document, however it is an acceptable surfacing for this application.
Please feel free to contact myself or American Hydrotech with any questions or concerns,
thanks.
Sincerely,
AMERICAN HYDROTECH, INC.
