The type of glass you choose impacts safety and cost. Most glass railings are constructed using tempered or laminated glass, both of which offer enhanced durability and breakage protection compared to standard glass:
- Tempered Glass: This type undergoes a process of heating and rapid cooling, which strengthens the glass and makes it more resistant to impacts. If it breaks, it shatters into small, less dangerous pieces, reducing injury risks. Its safety and resilience make it a popular choice, though it tends to be pricier than standard glass.
- Laminated Glass: Comprising two layers of glass with a thin plastic film between them, laminated glass adds another layer of protection. If damaged, the glass pieces stick to the plastic layer, minimizing hazards. This additional safety feature can slightly increase the cost.
Thicker glass panels are often required for higher stability, particularly in outdoor or high-traffic installations. While thicker panels provide enhanced safety and longevity, they also come at a higher cost. Additionally, local building codes may dictate minimum thickness requirements, typically ranging from ⅜ inch to ½ inch, further influencing the expense.
