Choosing the Right Glass Thickness: 5mm, 10mm, or 12mm Glass Railings Explained
When designing a space with an open, contemporary feel, glass railings have become a go-to choice for homeowners, architects, and builders alike. Whether you're looking to enhance your staircase, balcony, or deck, selecting the right glass thickness is crucial for both aesthetics and safety.
At Kelowna Rails, we specialize in glass railing installation and repair, and one of the most common questions we get is: “What glass thickness should I choose—5mm, 10mm, or 12mm?”
In this guide, we’ll break down the differences between 5mm, 10mm, and 12mm glass railings, how they’re used, and how to make the best choice for your project.
Understanding Glass Thickness in Railings
Glass railing systems provide a seamless and sophisticated look. But they aren't just about looks—they must meet safety standards and withstand environmental pressures, particularly in areas like Kelowna where snow, wind, and temperature shifts can affect materials.
Glass used in railings is tempered, making it much stronger than standard glass. But even tempered glass comes in various thicknesses. The three most commonly used types are:
- 5mm glass railing: Lightweight and budget-friendly
- 10mm glass railing: Balanced strength and style
- 12mm glass railing: Heavy-duty and premium option
Let’s explore the pros, cons, and ideal uses for each type.
5mm Glass Railing: Lightweight & Budget-Friendly
If you're working on a smaller interior space or a decorative element where strength isn't a top priority,
5mm glass railings might be the right fit.
Key Features:
- More affordable than thicker options
- Easier to cut and install
- Ideal for low-impact, decorative applications
Common Uses:
- Interior railings on short staircases
- Office partitioning
- Cabinet or shelving barriers

10mm Glass Railing: The Balanced Choice
Beyond their practical benefits, aluminum railing systems offer incredible versatility in design, seamlessly complementing a wide range of architectural styles. Whether your home boasts a contemporary, traditional, or minimalist aesthetic, there’s an aluminum handrail design to match. They can be powder-coated in a vast array of colors, allowing for complete customization to integrate perfectly with your existing decor. From sleek, minimalist picket railing designs to more ornate patterns, aluminum handrails can be tailored to create a truly unique and sophisticated look. This adaptability ensures that your safety handrails not only provide essential support but also contribute significantly to the overall beauty and value of your property. The ability to customize the finish means you can achieve anything from a bold, modern statement to a subtle, classic touch.
Key Features:

If you’re seeking a clean, durable, and safe railing system for a multi-use area, 10mm glass railings strike the perfect balance. At Kelowna Rails, this is one of our most requested thicknesses for its versatility and cost-effectiveness.
12mm Glass Railing: Strength Meets Style
When safety and aesthetics are both critical—such as in high-traffic areas or locations with a view—12mm glass railing becomes the clear winner.
Key Features:

Factors to Consider When Choosing Glass Thickness
Choosing the right thickness goes beyond aesthetics. Here are a few important things to keep in mind when selecting between 5mm, 10mm, or 12mm glass railing options:
1. Location
Exterior installations generally require thicker glass due to exposure to wind, temperature changes, and potential impacts.
2. Height of the Railing
Taller railings or those installed at greater heights (like second-story balconies) should use 10mm or 12mm glass for added safety.
3. Building Code Compliance
Local building codes in British Columbia often require a minimum thickness for glass railings, particularly in commercial settings. Kelowna Rails ensures all installations meet or exceed these requirements.
4. Design Preferences
For a minimalistic, modern glass stair railing look, many clients prefer frameless 12mm glass, which offers maximum visibility and style.
5. Budget
Cost can be a deciding factor. While 5mm glass railing is more affordable upfront, 10mm and 12mm options offer better durability, potentially saving money over time in repairs or replacements.

Frequently Asked Questions
What is the minimum thickness allowed for glass railings in Kelowna, BC?
Most residential and commercial codes in BC require a minimum of 10mm tempered glass for structural railings. Always check with your local municipality or consult Kelowna Rails for up-to-date compliance standards.
Can I use 5mm glass for outdoor railings?
While 5mm glass can be used indoors, we do not recommend it for exterior railings. It lacks the strength needed to withstand environmental forces such as wind or accidental impacts.
Is 12mm glass safe without a frame?
Yes, 12mm tempered glass can be safely installed without top or bottom framing, especially in frameless systems. However, it must be installed with the correct anchors and fittings to ensure structural integrity.
How much does a 10mm glass railing cost compared to 12mm?
10mm glass railings are generally 20-30% less expensive than 12mm options. The final cost depends on factors like hardware, length, and design features.
Do thicker glass railings require more maintenance?
Not necessarily. All glass railings require regular cleaning to maintain visibility and appearance, but 12mm glass may resist scratches and wear slightly better due to its thickness.
