Final Unit Flashcards
What performance criteria are common problems for selecting materials for interior partitions?
Strength, Durability, Fire Resistance, Acoustical Insulation
What materials are interior partitions usually made with?
Metal or Wood studs, face with plaster and gypsum board
-Concrete Block
What are the 5 types of interior partitions?
Fire walls, Shaft walls, Fire rated walls, Smoke barriers, and non-bearing or non-rated
How does a fire wall restrict the spread of fire to other parts of the building?
By dividing a single building into smaller fire components
Because a fire wall divides a single building into small components, what happens?
They are considered separate buildings when calculating heights and area as per code.
How far do fire walls extend?

What is the main purpose for a shaft wall?
To enclose a multi-story space like an elevator shaft or shafts for conduits and pipes.
What are the important characteristics of a shaft wall?
They have a 2+ Hour fire rating, they restrict floor-to-floor migration , they can withstand air pressure and suctions and of course, prevent elevator noise.
What material are shaft walls generally made of?
CMU Block or Gypsum Shaft Wall.
What is the purpose of fire-rated walls?
To restrict the spread of fire within a single building
The difference of a fire rated wall vs fire walls
They don’t have a wall that goes through the roof and are made of different materials
Fire walls generally separate what spaces?
Mixed occupancies or tenant spaces, hotel rooms and dorms, enclosed stairways and exit corridors.
Fire walls are usually made with what materials?
Metal framing with multiple layers or drywall and sometimes CMU block.
What are fire rated assemblies ?
Partition walls that are already constructed in a wall ready to be installed. They are tested by UL to meet ASTM standards and the must match UL assembly guides.
How do smoke barriers protect people from smoke?
They have a continuous air tight assembly with rated openings and doors.
