QUESTIONS AND CORRECT ANSWERS (VERIFIED ANSWERS) PLUS RATIONALES 2026 Q&A
|LATEST EXAM UPDATE 2026/2027.
Core Domains:
Glass and Glazing Safety Standards (ANSI Z97.1 and CPSC 16 CFR 1201)
Kentucky Building Code (KBC) Wind Load and Structural Requirements
OSHA Regulations and Job-Site Safety Protocols
Sealants, Gaskets, and Weatherproofing Installation
Aluminum Framing Systems and Storefront/Curtain Wall Design
Contract Administration, Estimating, and Project Management
Introduction:
The purpose of the Kentucky Glazing Contractor Certification Examination is to evaluate the technical
competence, practical knowledge, and regulatory compliance capacity of professional glazing contractors
operating within the Commonwealth. The assessment covers fundamental theory, material science,
structural engineering principles for fenestration, and complex site safety requirements. Emphasizing
real-world application and decision-making, the examination utilizes a rigorous combination of direct
knowledge inquiries and practical scenario-based problems. Candidates are tested on their ability to
interpret building codes, select appropriate glazing materials for specific impact and wind exposure
zones, and manage operational safety under state and federal mandates.
What is the primary standard referenced by the Kentucky Building Code for evaluating the impact
performance of safety glazing materials in hazardous locations?
A. ASTM E330
B. ANSI Z97.1
🟢 C. CPSC 16 CFR 1201
,D. ASTM E283
🔴 RATIONALE: CPSC 16 CFR 1201 is the federal standard mandated by building codes for
safety glazing in hazardous locations such as doors and shower enclosures, mirroring testing
criteria found in ANSI Z97.1 but carrying regulatory enforcement.
According to OSHA standards, at what fall height above a lower level must workers on a
construction site installing exterior curtain walls be protected by conventional fall protection
systems?
A. 4 feet
B. 10 feet
🟢 C. 6 feet
D. 15 feet
🔴 RATIONALE: OSHA standard 1926.501 requires fall protection for employees working on
walking/working surfaces with an unprotected side or edge that is 6 feet or more above a lower
level.
When calculating design wind loads for a storefront framing system in a high-wind Kentucky
county, which factor does NOT directly affect the net design wind pressure?
A. Basic wind speed
B. Glass thickness tolerance
🟢 C. Exposure category
D. Internal pressure coefficient
🔴 RATIONALE: Glass thickness manufacturing tolerances affect structural capacity but are not a
variable in calculating the environmental net design wind pressure (p) dictated by ASCE 7 and the
building code.
Which ASTM test method governs the structural performance of exterior windows, curtain walls,
and doors under uniform static air pressure difference?
,A. ASTM E283
🟢 B. ASTM E330
C. ASTM E331
D. ASTM E2112
🔴 RATIONALE: ASTM E330 determines the structural performance of exterior fenestration
assemblies when subjected to uniform static air pressure differences, simulating positive and
negative wind loads.
What is the minimum nominal thickness required for fully tempered glass installed in a sliding glass
door panel where the exposed surface area exceeds 9 square feet?
A. 1/8 inch
B. 1/4 inch
🟢 C. 3/16 inch
D. 3/8 inch
🔴 RATIONALE: Building codes specify minimum thicknesses for fully tempered safety glass
based on area; panels over 9 square feet typically require at least 3/16 inch nominal thickness to
meet impact resistance ratings.
Which type of sealant is generally recommended for structural silicone glazing applications due to
its superior UV resistance and movement capability?
A. Acrylic latex
🟢 B. Neutral-cure silicone
C. Polyurethane
D. Acetoxy-cure silicone
🔴 RATIONALE: Neutral-cure silicones do not release corrosive byproducts during cure and offer
excellent long-term resistance to ultraviolet radiation, weathering, and high joint movement
required in structural sealant glazing.
, Under OSHA regulations, how often must a competent person inspect scaffolding used by glazing
crews on a high-rise project?
A. Monthly
🟢 B. Before each shift and after any occurrence that could affect structural integrity
C. Weekly
D. Only upon initial setup
🔴 RATIONALE: OSHA requires competent person inspections of scaffolding prior to each work
shift and after any event that could compromise the safety or integrity of the scaffold system.
What is the primary purpose of setting blocks installed beneath a sealed insulating glass unit within
an aluminum frame?
A. To block water infiltration
🟢 B. To support the weight of the glass and center it within the pocket
C. To thermally insulate the glass edge
D. To absorb seismic energy
🔴 RATIONALE: Setting blocks (usually resilient neoprene or EPDM) transfer the dead load of the
glass directly to the framing system and maintain uniform edge clearances around the perimeter.
In a dual-seal insulating glass unit, what is the primary function of the inner secondary seal?
A. To provide structural rigidity against wind load
🟢 B. To act as a moisture vapor transmission barrier protecting the primary desiccant
C. To absorb UV radiation from the sun
D. To enhance acoustic dampening
🔴 RATIONALE: The secondary structural seal (commonly polyurethane or silicone) provides
structural strength and acts as the principal barrier preventing ambient moisture vapor from
entering the unit and degrading the desiccant.
