1. What is the primary responsibility of a Florida Glass & Glazing
Contractor?
To install, repair, or replace glass, glazing, and related components in
compliance with Florida building codes.
Rationale: The contractor must follow Florida laws and building
codes to ensure safety and compliance in all glass and glazing
projects.
2. Which type of glass is commonly used in hurricane-prone areas of
Florida?
Laminated glass
, Rationale: Laminated glass holds together when shattered, providing
protection against high winds and flying debris.
3. What is the minimum safety standard for glazing in doors, windows,
and other hazardous locations?
Safety glazing as per ANSI Z97.1 and CPSC 16 CFR 1201
Rationale: These standards define safety requirements to reduce the
risk of injury from broken glass.
4. What is the maximum allowable deflection for a tempered glass panel
in a window frame?
L/175
Rationale: Building codes limit deflection to ensure the glass can
withstand wind loads without breaking.
5. Which sealant type is typically used for exterior glass installations?
Silicone sealant
Rationale: Silicone sealants provide weatherproofing, UV resistance,
and flexibility for glass in exterior applications.
6. When installing insulated glass units, why is it important to use a
desiccant?
To absorb moisture and prevent condensation inside the unit
Rationale: Desiccants maintain the clarity and thermal efficiency of
insulated glass units by keeping the air space dry.
,7. What safety equipment is required when cutting glass on site?
Safety glasses, gloves, and protective clothing
Rationale: Personal protective equipment prevents injuries from
sharp edges, flying shards, and dust.
8. What type of frame material is most resistant to corrosion in coastal
Florida?
Aluminum with anodized or painted finish
Rationale: Aluminum resists corrosion and, with proper finishing,
withstands the harsh coastal environment.
9. When glazing a storefront, what is the standard method for measuring
glass?
Measure the opening and subtract appropriate clearance for spacers
and sealant
Rationale: Accurate measurements ensure proper fit and
accommodate expansion, contraction, and sealant thickness.
10. What is the minimum thickness of tempered glass required for a
36-inch by 36-inch window subject to wind load?
1/4 inch (6 mm)
Rationale: Building codes specify minimum thickness for safety and
structural integrity under wind pressure.
11. What is the main difference between annealed and tempered
glass?
Tempered glass is heat-treated for strength and breaks into small,
, blunt pieces
Rationale: Tempering increases strength and reduces injury risk
compared to annealed glass, which breaks into sharp shards.
12. How often should glass in doors and windows be inspected for
damage?
At least annually
Rationale: Regular inspections detect cracks, chips, and seal failures
before they compromise safety or energy efficiency.
13. What is the purpose of a backer rod in glazing applications?
To control the depth of sealant and provide a proper seal
Rationale: The backer rod prevents three-sided adhesion, allowing
sealant to flex and maintain a watertight seal.
14. Which type of glass is commonly used for skylights to reduce
solar heat gain?
Low-E coated glass
Rationale: Low-emissivity coatings reflect infrared energy, reducing
heat transfer and improving energy efficiency.
15. When installing tempered glass, how should it be handled to
avoid breakage?
Lift and carry vertically, avoid sliding or dragging
Rationale: Tempered glass is strong under normal use but can
shatter if edge impact occurs, which is minimized by proper handling.
