Frameless Glass Railing – Glass Types and Technical Standard

The frameless glass railing is very important structures for safety in high-rise places such as balconies and stairs. It serves as a barrier to prevent falls and maintain the integrity of people using the facility’s facilities.

The railing structure can be made with different materials such as metal and wood, however, glass is becoming increasingly common in these projects due to the practicality, modernity and sophistication it offers.

Despite the advantages that the material offers in this type of application, it is necessary that the glazier and other professionals involved always follow all the guidelines stipulated by the technical standards. They guarantee the correct execution of the projects and protect those involved from legal responsibilities if the installation presents any problem caused by misuse or factors that are beyond the professionals’ attributions.

In the case of frameless glass railing, the standards include the requirements, procedures and test methods, which are essential for the installers’ repertoire. To help you understand the standard, we have prepared the following content, with an explanation of the main requirements determined by it:

Technical Standards for frameless glass railing projects

Glass type

The glass used for the installation of frameless glass railing must always be laminated. It offers more resistance and does not spread the shards in case of breakage, in addition to preventing the opening of gaps in the material.

It is also possible to use tempered laminate, which combines the safety properties of both types of glass.

Measurement and definition of clearances

This is a crucial step that must be defined at the beginning of the project. A mistake made during this process will cause the entire installation to be done incorrectly.

Height: To ensure the safety of the installation, the frameless glass railing must be at least 1.10 m high.

Spacing between spans: In some cases, the guardrails completely has only one sheet of glass. But in others there may be gaps for the application of hardware. If the installation follows the frameless glass railing model, the free space between the glasses must have a maximum of 0.11 m.

Spacing between non-parallel profiles: The structure may have spans between ornaments that are not arranged in straight and parallel lines. In this case, the spacing reference is a prismatic template of 0.25 m × 0.11 m × 0.11 m. In short, no object larger than this volume can pass through the spaces between the profiles.

Spacing between the lower part of the guardrail and the floor: The gap created between the space of the lower horizontal part of the guardrail and the outer edge of the pavement cannot allow the passage of a spherical template with a diameter of 0.09 m.

Anchoring the guardrail

To properly fix the guardrail, the standard determines that the anchorage in the concrete must be at least 70 mm deep, disregarding the thickness of other existing coatings such as floors and porcelain tile.

Unevenness

The standard recommends that in areas with slopes greater than 0.10 m, apply an extension of the guardrails of at least 0.30 m after the end of the upper level. Most people do not like this orientation on stairs or ramps.

Free Pass

All along the frameless glass railing there can be no gap that allows the passage of a sphere with a diameter of 0.05 m rolling along the floor. This orientation helps prevent objects on the upper levels from falling and harming users on the lower level.

Types of glass to use in frameless glass railing installation

The guardrail has the function of protecting users around it, working as a half-height barrier in uneven environments such as balconies and stairs, both indoors and outdoors. 

A consolidated trend in the construction market is frameless glass railing, as they bring more lightness to the project.

To ensure this safety, the standards recommend the use of laminated glass. Laminated glass is suitable when there is a need for greater strength, such as in guardrails, floors, stairs, pool windows and roofs. Within this type of glass there are variations to consider, such as tempered laminated glass and wired glass. There is also the possibility of combining other types of glass to form the laminate, such as applying printed or colored glass to one of the sheets. You can also use the colored PVB films in your project to generate colored glasses.

Laminated glass

Laminated glass is a safety glass. It consists of one or more layers of glass, interspersed by one or more interlayers. They can be Polyurethane, EVA or resins. The laminated glass can be flat or curved.

Laminated tempered glass

The laminated tempered glass consists of laminating two or more pieces of tempered glass.

The set brings together the qualities of two products in addition to the safety. It has essential characteristics for various types of application. It is five times more resistant than a common laminated glass of the same thickness. This type of glass blocks up to 99.6% of ultraviolet radiation. It is possible to create several variations in tempered-laminated glass with the combinations of different types of glass.

If the railing has a fastening hardware or self-support, the tempered-laminated glass is most suitable. It offers even more resistance by uniting the properties of tempered and laminated. It is ideal for applications that require holes and accessories.

Wire glass

Wire glass is also a safety glass because it has a checkered mesh metal mesh incorporated into its mass.

The guardrail has the function of protecting users around it. It works as a half-height barrier in uneven environments such as balconies and stairs, both indoors and outdoors. A consolidated trend in the construction market is glass railings, as they bring more lightness to the project.
