Glass railing is the most popular railing choice for modern Ontario staircases — and the one with the most questions about code compliance, durability, and maintenance. This guide covers glass type selection, system types, and real installation costs.
Tempered vs Laminated Safety Glass
| Property | Tempered Glass | Laminated Glass |
|---|---|---|
| How it’s made | Heat-strengthened then rapidly cooled | Two layers bonded with PVB interlayer |
| Strength | 4–5× stronger than annealed | Stronger + holds together on failure |
| Failure mode | Shatters into small safe fragments | Cracks but holds — no fall-through risk |
| Typical thickness | 10mm or 12mm | 8mm + 8mm = 16mm total |
| OBC compliance | Yes | Yes |
| Cost | Lower | Higher (+15–20%) |
C.O.R.S uses 12mm tempered safety glass as standard — OBC compliant, extremely strong, cleanest visual result.
Frameless vs Semi-Frameless Systems
Frameless Glass Railing
Glass panels supported by base shoe channels with no visible posts. Near-invisible appearance. Highest cost — precision base shoe fabrication and technical installation. A separate graspable handrail at 865–965mm is required alongside.
Semi-Frameless Glass Railing
Glass panels secured by visible steel posts every 900–1,200mm. More forgiving installation. If the top rail is graspable at 865–965mm, it satisfies the handrail requirement. Moderate cost.
Glass Railing Costs in Ontario (2025)
| System Type | Cost (12-Tread, One Side) |
|---|---|
| Semi-frameless, powder-coated posts, 10mm tempered | $3,500 – $5,500 |
| Semi-frameless, stainless posts, 12mm tempered | $4,500 – $7,000 |
| Frameless, black base shoe, 12mm tempered | $5,500 – $8,500 |
| Both sides (open staircase) | Add 60–80% to one-side cost |
Maintenance
- Weekly wipe with glass cleaner typical in family homes
- Use a squeegee after cleaning in hard-water areas (Barrie and Simcoe County have moderately hard water)
- Broken panel can be replaced individually — typical cost $400–$800
