# Diff notes — double-pane-or-triple-pane-windows

## Scope
Full educational refresh of the live comparison article for primary intent **double vs triple pane windows** (Canada). Keep structure recognizable; fix claim risk, heading case, broken tables, and commercial fence. Voice: confident, helpful CCW. No CLEAN.docx in this pass (markdown + annotated review only).

## Intent / uniqueness
1. **This URL owns** the informational double vs triple pane comparison for Canadian homeowners.
2. **One mid-body soft link** to `/windows.html` (anchor “windows”) in the choose section.
3. **Fence:** no buy/price-first framing; remove Halifax product digression; drop speculative ROI / payback %.

## Facts / compliance
- Softened unverified **10–20% bill savings**, **5–10 year payback**, table “better ROI,” and Tony “pays off within a few winters.”
- Removed frame-material list that implied wood / fibreglass / aluminum as CCW options; CCW = **uPVC casement**, Canadian-made, DraftLOCK, **25-year transferable warranty**.
- Kept directional industry R-value bands (R-3 to R-5 vs R-6 to R-9) with “typical / often” caveats; not product guarantees.
- Retained live **Helen Sin** quote (already published). Removed Tony Wong payback quote.
- No new Helen/Tony quotes.

## Structural / SEO
- Rewrote intro to lead with a **short answer** for comparison intent.
- Sentence-case H1/H2/H3; removed em dashes.
- Rebuilt one accurate comparison table (filled pane/cavity cells; qualitative cost row).
- Dropped the second garbled “Choosing Between…” table (climate cells wrong/blank).
- Meta: drop ROI / em dash; title softens Cost/ROI tilt.
- FAQ tightened; speculative payback answer reframed.
- Kept three live S3 content images (hero + double cross-section + triple PVC).

## Length
- Live noisy body ≈ **2,250** → refreshed ≈ **1,490** (H1→end). Tighter, on-intent; not padded.

## Left alone
- URL slug unchanged.
- Core section flow (what is double / triple → compare → climate → install → choose → FAQ → CTA).
- Live Helen quote wording.
- Live content image URLs.
