Supporting Weather Barriers

Thermal bridging is ________

• the movement of air molecules

• the transfer of heat and cold through the building envelope

• the heat from the sun

• the measurement of how much heat transfers from one side of material to another

Examples of exterior finish weather barriers are

• shaft walls, stairwells, sprinkler rooms, and candy bars

• insulation, rockwool, fiberglass, and WMP

• metal panels, brick veneer, CMU veneer, phenolic panels, and fiber cement panels

• vapor barriers, caulks, metal stud framing, and sheetrock

What does CFS stand for?

• composite framing support

• complicated framing structures

• complex fabricated systems

• continual framing sequence

Examples of a building structure substrate are________

• topsoil, beauty bark, and hydro seeding

• metal panels, mullions, and glazing

• doors, windows, louvers, and vents

• dense glass, plywood, masonry, and concrete

Composite Framing Support (CFS) systems use composite materials that are structurally sound and fire resistant.

• TRUE

• FALSE

CFS’s have extruded profiles, such as a/an ______ shape, or individual clips that are secured to the building substrate with screws.

• 'U'

• 'Z'

• 'C'

• 'L'

CFS’s perform two tasks:

• hold insulation in place, and provide attachment for weather barriers

• add structural support around window openings and other penetrations

• keep the building looking new, and well built

• hold the exterior sheathing in place, and complete the air barrier

CFS's are made from a fiber-reinforced polymer that’s used in combination with sheet metal strips, tabs, or ‘Z’ girts

• TRUE

• FALSE

The insulation used most often in CFS systems is typically fiberglass insulation

• TRUE

• FALSE

When additional work is requested it is a good habit to

• do the work with no questions asked

• turn it down and leave it for someone else

• take personal bribes and do the work "under the table"

• get written permission to proceed on scope changes
