The foundational explainer every Canadian fabricator and specifier needs. How a 0.2mm vacuum cavity eliminates conduction and convection entirely, why argon gas in conventional IGU degrades over time, and how VIG achieves U=0.40 W/m²K in 8.2mm where triple pane needs 36mm — with the performance comparison data to prove it.

How a 0.2mm vacuum gap eliminates convection entirely and achieves U=0.40 in 8.2mm.
NBC 2020 → Step Code 5 → Quebec CCQ → 2025 GHG limits. The regulatory trajectory every fabricator must understand now.
Frame pockets of 6–10mm. Triple pane needs 36mm. A deep dive for heritage restorers and designated-building architects across Canada.
Argon gas decays 1% per year. Triple-pane performance degrades 15% by year 30. VIG's vacuum never leaks. Delta U = 0.00.
CAN/CGSB 12.1-2022 COMP+CAN explained. How to verify a cert at sgcc.org. What to look for — and what to avoid.
EN 673 vs NFRC 100. ER ratings. SHGC. How the 2025 NECB changes SHGC requirements. Where VIG sits on each metric.
VIG needs surface flatness under 0.05mm. Standard tempering produces 0.15–0.30mm roller wave. What Glaston FC500 does differently.
