# Diff notes — argon-gas-windows-benefits-and-drawbacks

## Major adds

- One-sentence banner intro after hero (argon as standard IGU fill).
- `## H2: Key takeaways` with six scannable bullets (replaces live `H3: Key Takeaways:`).
- Dedicated sections: what argon does in IGUs, lifespan timeline, maintenance/replacement guidance, FAQs.
- Qualitative argon vs krypton vs air table retained and expanded (DraftLOCK row).
- Soft mid-body link to [windows.html](https://www.windowscanada.com/windows.html) in CCW product context.
- **25-year transferable warranty** on sealed glass failure.
- Cannibal fence links to sibling `argon-gas-windows-vs-double-pane-what-offers-better-efficiency.html` (pane count, not full rewrite here).
- NRCan / ENERGY STAR Canada referenced conceptually (no invented savings %).
- uPVC casement + DraftLOCK argon standard language per `facts.md`.

## Major deletes / demotions

- Live **Locations** widgets and city commercial links (Charlottetown, Vancouver, Mississauga, Ottawa, etc.).
- **Norman Verblonski** quote (SOP: Helen/Tony only); retained live **Helen Sin** quote.
- Invented **$40 per window** upgrade cost and “lower energy bills” as guaranteed outcome.
- Numbered benefit H3s (`1. Improved Appearance`, etc.) → plain sentence-case H3s.
- Misleading “resealing windows can prevent further gas loss” → IGU replacement when seal fails.
- Toronto five-year anecdote (generic Canadian pattern instead).
- Title Case headings throughout.

## Why (summary)

Live page lost clicks (−42.4%) with weak scan structure (H3 takeaways), commercial location dumps, unapproved quote voice, and claim risk ($/window, reseal myth). Refresh owns **argon gas windows** education (benefits, drawbacks, lifespan), fences pane-count intent to the sibling URL, and aligns with CCW brand/SOP like the black-mould refresh.
