Does anyone know of a good through-penetration firestopping product that provides IBC required T-rating and F-rating?
Do stacked electrical closets require a t-rating?... I was a little confused by the IBC language seems like if conduits enter floor mounted equipment it would not but otherwise it would be required.
I recommend reaching out to Hilti or 3m as they have specialists that do this as their primary job and they are eager to explain.
