Retrofit Firestop Collars
I saw in your firestop approval for retrofit fire collar, it only covers penetration through flexible wall or framed wall, however I have a concrete wall. Can I still use fire collar?

In the Fire Test standard AS1530.4, it states that the results obtained from framed wall systems may be applied to the performance for a system in concrete, masonry systems and solid gypsum block of greater or equal thickness to that of the tested prototype. The reverse does not apply.
