Sample AL Doors Windows Glass Practice Questions

Try these sample questions to test your AL Doors Windows Glass exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under the International Building Code (IBC), glazing in which of the following is generally considered a hazardous location requiring safety glazing?
A.High clerestory windows more than 8 feet above the floor
B.All fixed and operable panels of swinging, sliding, and bifold doors
C.Transom glass above 7 feet with a protective guardrail
D.Spandrel panels behind a solid knee wall
Explanation: IBC Section 2406.4.1 treats glazing in all fixed and operable panels of swinging, sliding, and bifold doors as a hazardous location. Impact-resistant safety glazing (typically tempered or laminated) is required unless a listed exception applies.
2Per IBC glazing-adjacent-to-door rules, safety glazing is typically required when the nearest vertical edge of the glass is within what horizontal distance of a closed door and the bottom of the glass is less than 60 inches above the walking surface?
A.12 inches
B.18 inches
C.24 inches
D.36 inches
Explanation: IBC 2406.4.2 identifies glazing adjacent to doors as hazardous when the nearest vertical edge is within a 24-inch arc of either vertical door edge and the bottom exposed edge is less than 60 inches above the walking surface. Sidelights next to doors commonly trigger this requirement.
3Which breakage pattern is characteristic of fully tempered glass?
A.Long, sharp dagger-like shards
B.Small granular cubes that are less likely to cause severe lacerations
C.Cracks that stop at a plastic interlayer while the sheet stays in the opening
D.A spiderweb pattern that always remains fully bonded to the frame
Explanation: Fully tempered glass is heat-treated so residual surface compression causes it to dice into small, relatively blunt cubes on breakage. That behavior is why tempered glass qualifies as safety glazing under impact standards such as CPSC 16 CFR 1201.
4Laminated safety glass stays in the opening after impact primarily because of which component?
A.A metal wire mesh embedded in the glass
B.A plastic interlayer, commonly PVB, bonded between glass plies
C.A low-e coating on surface #2
D.Argon gas fill in the air space
Explanation: Laminated glass sandwiches one or more plastic interlayers (often polyvinyl butyral, PVB) between glass plies. On impact the glass may crack, but the interlayer holds fragments together and helps retain the lite in the opening.
5According to NFPA 80, fire door assemblies must generally be inspected at least how often after initial installation?
A.Monthly
B.Quarterly
C.Annually
D.Every five years
Explanation: NFPA 80 requires fire door assemblies to be inspected and tested after installation and then at least annually. Inspections verify labels, clearances, hardware function, positive latching, and overall integrity of the rated assembly.
6A labeled fire door assembly is generally required to do which of the following when released from the open position?
A.Remain ajar for free ventilation
B.Self-close and positively latch
C.Swing freely without a latch bolt
D.Hold open with a mechanical prop
Explanation: Fire doors must be self-closing (or automatic-closing where permitted) and must positively latch so the door remains closed under fire conditions. Unlatched or propped-open fire doors defeat the rated opening protective.
7On a National Fenestration Rating Council (NFRC) label, a lower U-factor indicates that the window:
A.Admits more solar heat
B.Transfers less heat and insulates better
C.Has higher visible light transmission
D.Leaks more air at the operable sash
Explanation: U-factor measures the rate of non-solar heat transfer through the entire fenestration product. A lower U-factor means better thermal resistance and improved insulating performance for heating and cooling loads.
8What does the Solar Heat Gain Coefficient (SHGC) on a window primarily describe?
A.Resistance to condensation on the indoor glass surface
B.Fraction of incident solar radiation admitted through the product as heat
C.Sound transmission loss of the assembly
D.Structural design pressure rating of the frame
Explanation: SHGC is the fraction of incident solar radiation admitted through a window as heat, including transmitted solar radiation and absorbed heat later released inward. Lower SHGC values reduce cooling loads in hot climates.
9Under OSHA construction fall-protection rules (29 CFR 1926 Subpart M), workers on unprotected sides and edges are generally protected at what height above a lower level?
A.4 feet
B.6 feet
C.10 feet
D.15 feet
Explanation: For construction under Subpart M, fall protection is generally required at 6 feet or more above a lower level on unprotected sides and edges. Door, window, and glass installers working at openings and on scaffolds must plan for this trigger height.
10ADA Standards generally require a minimum clear opening width of how many inches for an accessible door measured with the door open 90 degrees?
A.28 inches
B.30 inches
C.32 inches
D.36 inches
Explanation: ADA Section 404.2.3 requires at least 32 inches of clear width, measured from the face of the door to the stop on the latch side with the door open 90 degrees. A 36-inch nominal door is commonly used to achieve that clear opening.
