What is the difference between Hi-Temp Silicone “Red” and Firestop?
Regular Silicone has a service temperature of -40 to 400F (multi-colors) (Boss 315 is an example).
Hi Temp Silicone has a service temperature of -40 to 500F (red) (Boss 376 is an example).
FireStop Silicone has a service temperature of -40 to 500F (red) (Boss 760 is an example) – the main difference between Hi-Temp Silicone and Firestop Silicone is that Firestop Silicone has undergone more testing and has more spec’s that allows it to be called FireStop.
Where are they used application wise?
Hi-Temp silicones: are used by many contractors near furnaces, while industrial maintenance people will use near motors as a precaution.
FireStop silicone: is designed for HVAC fire dampers in ventilation.
What is the difference between FireSTOP and FireBLOCK?
Often Fire Block and Fire Stop are confused by contractors and our industry doesn’t do much to help.
FireBlock (Red in color) is used to slow or stop the migration of smoke from one area to another. No stopping of flame! (Boss 136 is an example)
FireStop (also Red in color) is a product used either by itself or as part of a UL system and its purpose is to either slow or stop the spread of flames.
Boss makes two levels of FireStop used in two different types of construction.
Boss 814 is used mostly in wood frame construction like three stories or less, such as hotels, dorms, and apartments.
Boss 816+ is used in wood, steel and concrete construction, mid- and high-rise structures (it offers more UL Systems).
