What to know
- Compare Energy Rating and U-factor for the complete product, not a centre-of-glass claim.
- The comfort and noise case is often clearer than a simple payback spreadsheet.
- Heavier glass needs hardware and balances rated for the weight.
What you actually buy
Triple glazing puts two gas-filled cavities between three panes, usually with Low-E coatings. Rooms feel less cold next to the glass, condensation risk drops, and street noise drops a notch. In cold provinces the energy case is stronger than in coastal B.C.
The marketing label is not the comparison. Ask for the certified whole-product U-factor and Energy Rating for the size you are buying.
