Year 3 Exam Study Guide — master what the exam actually tests, concept by concept.
Building codes, fire codes, and workplace regulations define the minimum standards that protect occupants and workers. These aren't guidelines — they're legal requirements. Knowing your applicable codes means fewer failed inspections, less rework, and a professional reputation that lasts.
Blast glass: thick lamination distributes load; frame must anchor glass perimeter (every 12-18 inches) to resist pressure/impact. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Passive House windows: U <0.15-0.20, SHGC <0.20. Triple-glazed, insulated frame, krypton/argon fill, advanced coatings. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Glass railing: codes specify load (IBC 200 lbs horizontal, 300 lbs concentrated at 42" height). Tempered safety glass, tested frame. Understanding and applying code requirements correctly ensures your installations pass inspection and meet legal obligations in your jurisdiction.
Retrofit glazing: existing frame must be true and sound. Out-of-square or damaged frame causes glass stress and seal failure. Troubleshooting is a systematic process: identify symptoms, narrow down causes logically, and verify your diagnosis before replacing parts. This logical approach is what examiners want to see.
Structural calculations, material quantities, load calculations, and slope determinations are all part of journeyperson knowledge. These questions test your ability to move between units, apply geometric principles, and size materials correctly for the application.
Rainscreen: equalized pressure chamber prevents pressure-driven water infiltration. Water sheds by gravity; drains to weep holes. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Acoustic laminate: soft PVB interlayer damps sound vibration. STC 45+ achievable; low frequencies (bass) hardest to attenuate. Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Smart glass: lithium ions migrate between coatings under voltage, changing opacity. Variable shading reduces cooling load/glare. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Construction materials have specific strengths, limitations, and proper applications. Choosing the wrong adhesive, fastener, or structural member isn't just a quality issue — it can be a structural failure waiting to happen. Know your materials.
Structural silicone: high-modulus sealant bonds glass to frame; accommodates thermal/wind movement. ±50% movement typical for good sealant. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Laminated glass: PVB interlayer holds shards together on breakage, maintaining opening barrier. SGP stiffer, better for hurricane/blast. Safety regulations exist because the consequences of ignoring them are severe — injury, death, or legal liability. Know these requirements the way you know your own name.
Wind-resistant: closer fasteners, sealed joints, structural silicone resist wind pressure (40-150 psf potential). ASTM E330 testing. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
