Is it possible to use CPVC pipe to protect the floor below in an attic that is completely filled with insulation?

If the attic requires a fire sprinkler system, BlazeMaster CPVC can be used with special
sprinkler heads for this circumstance. If the attic does not require a fire sprinkler system,
BlazeMaster piping can still run through to protect the floor below, but please follow the
manufacturer’s listing. **Special heads that could be used in this circumstance are Tyco’s
Combustible heads- CC1, CC2 and CC3.
