1. Which of the following best describes the primary purpose of curtain
wall systems in commercial construction?
A. Load-bearing structural support for multi-story buildings
B. Waterproofing underground foundations
C. Exterior non-load-bearing envelope designed to resist weather and
improve aesthetics
D. Lightweight exterior façade system that resists wind, water, and
air infiltration without carrying structural floor loads
Curtain wall systems are non-structural exterior envelopes that
protect buildings from environmental elements while allowing light
and design flexibility, without supporting building loads.
2. In Maryland construction practice, curtain wall installation work is
most commonly classified under which trade category?
A. Electrical contracting
B. Heavy civil engineering
C. HVAC systems installation
, D. Glass and glazing / exterior building envelope trades
Curtain wall installation is part of glazing and façade systems,
typically grouped under glass and architectural envelope trades
rather than mechanical or structural construction disciplines.
3. A key performance requirement of a properly installed curtain wall
system is:
A. Load transfer to foundation piles
B. Electrical grounding of façade panels
C. Reinforced concrete compression strength
D. Resistance to wind loads, water penetration, and air leakage
Curtain walls must maintain building enclosure integrity by resisting
environmental forces while accommodating movement and thermal
expansion.
4. Which component is most directly responsible for supporting glass
panels in a curtain wall system?
A. Rebar cages
B. Steel beam girders
C. Concrete footings
D. Aluminum mullions and framing members
Curtain walls typically rely on aluminum framing systems, especially
vertical and horizontal mullions, to support glazing units.
5. What distinguishes a curtain wall from a storefront system?
A. Curtain walls are always made of steel
B. Storefront systems are load-bearing
C. Curtain walls are used only indoors
D. Curtain walls can span multiple floors and are not limited to
ground level applications
Curtain walls are designed for multi-story façades, whereas
, storefront systems are generally limited to ground-floor commercial
applications.
6. The most common infill material used in modern curtain wall systems
is:
A. Brick masonry
B. Structural concrete panels
C. Wood panels
D. Insulated glass units (IGUs)
Insulated glass units are widely used due to their thermal efficiency,
daylighting capability, and aesthetic flexibility.
7. A major safety concern addressed during curtain wall installation is:
A. Soil compaction failure
B. Electrical short-circuiting in rebar
C. Fuel combustion in concrete mixers
D. Fall hazards and working at elevated heights
Curtain wall installation often occurs on scaffolding or elevated
platforms, making fall protection a critical safety requirement.
8. Which certification is most commonly associated with glazing and
curtain wall performance testing?
A. Plumbing inspection certification
B. Welding metallurgy license
C. Road paving technician license
D. Glazing and architectural metal testing certifications such as
AGMT-related credentials
Glazing certification programs assess skills specific to façade systems,
including curtain walls and storefront assemblies.
9. Thermal expansion in curtain wall systems is primarily accommodated
by:
A. Cement bonding agents
