Is 10mm Glass Safe for Deck Railings? Alberta Code Says No
Alberta's Strict Minimum
At Innovative Railing and Decks, we get asked this a lot: can 10mm tempered glass pass for your Calgary deck project? Short answer — no, and here’s why based on the latest SGCC certifications and local code.
Alberta Building Code (Part 9, Sentence 9.8.8.3) requires fully tempered or laminated safety glazing at least 12mm thick for guards. This handles real-world loads (0.5 kN/m horizontal) plus CAN/CGSB-12.1 impact testing — vital for decks over 600mm high.
What the Certificates Reveal
We’ve reviewed two fresh SGCC docs for Shandong suppliers:
- Qingdao Laoyou: Certifies 10mm TTG to COMP-CAN, ANSI Class A.
- Qingdao Laurel: Covers 10mm (7.3/10mm range) same standards.
- They ace safety tests, but 10mm still fails the 12mm thickness rule. Inspectors won’t budge — permit delays ahead.
Go 12mm for Peace of Mind
Both certs greenlight 12mm options perfectly for Alberta decks. Skip the risks: failed inspections, rework, liability.
