Q

Describe Fire Partitions

A

Fire partitions are the least restrictive of the 3 assemblies. They have the minimum Fire-resistance rating of 1 hour. Most commonly used to separate dwellings or sleeping units. T shape with 3’ either side of partition

Q

Describe Fire Barriers

A

Fire barriers include walls and horizontal assemblies. They vary ratings between 1-4 hours. They separate occupancy classifications.
They must be continuous through concealed locations. Like the space above a suspended ceiling. Full T shape
