Frequently Asked Questions
Our TransLevel TL-4010 glass balustrade system has been subjected to static calculations for high glass panels up to 1.4 meters (fall-proof balustrade) and 2.5 meters (partition without fall risk). For high glass balustrades, it is strongly recommended to consider the applicable wind load.
A glass balustrade is an excellent choice for adding both safety and style to your balcony or rooftop terrace. It provides protection against the wind and ensures that you can enjoy the beautiful view without any obstructions. It is a modern and elegant solution for your outdoor space. As a general rule, a railing is required when the fall height is greater than or equal to 1 meter or when the slope is greater than 45 degrees.
There are various TransLevel profiles in which curved glass can be mounted. It is also possible to bend handrails and Top-Cover profiles. Bending is possible with a minimum radius of 1 meter. Do not hesitate to contact us for more information.
The Flex Fit glass mounting system integrated into the TransLevel profiles allows for fixing glass thicknesses from 12.76 mm to 31.52 mm. The glass panels can be laminated with various types of films, such as PVB and PVB DG41. In the Netherlands, PVB film is the most common.
The minimum glass thickness for a glass balustrade depends on the user function, mounting method, location, and height. For a full glass balustrade, a minimum glass thickness of 16.76 mm is recommended to ensure effective fall protection. For situations on a concrete edge, thus with reduced glass height, glass of 12.76 mm can be used. When using a system with aluminum balusters, glass of 10.76 mm is sufficient. Different types of glass can be used. In the Netherlands, toughened laminated glass is most commonly used. The most common glass thicknesses are 88/4 and 1010/4.
Absolutely, maintaining aluminum is essential to ensure durability and preserve the warranty of the glass balustrade. Regularly cleaning the aluminum with a soft cloth and cleaner can prevent the buildup of dirt and corrosion.
Absolutely. Our TransLevel glass balustrade systems are designed to be applied to staircases with an angle of up to 40° relative to the horizontal.
ONLEVEL offers a wide range of cover caps compatible with the TransLevel profile range. The 'Top Cover' caps ensure a consistent aesthetic in a project by offering options suitable for different types of cladding, such as decking strips, custom plates, wood cladding, stone, etc. They are designed to fit various cladding thicknesses, ranging from 3 mm to 120 mm, and are available in vertical and horizontal versions.
FLEXFIT is the perfect system for precise adjustment of glass panels. With FLEXFIT, you can individually adjust each glass panel up to 34 millimeters relative to the plumb line during installation. With a simple sliding movement, you can accurately set the glass, reducing installation time by about 30%. FLEXFIT can be optionally applied in all TransLevel glass profiles for glass thicknesses from 12 to 31.52 mm. Traditional systems often require processing from both inside and outside. FLEXFIT is used exclusively from the walking side. This applies to the entire installation, making it not only much safer but also saving you unnecessary costs for scaffolding or a cherry picker.

According to NEN/EN 1991-1-1, there are three types of line loads categorized into five user classes:
Private application (0.5KN; category A and B): Toughened laminated 8/8/4 (17.52 mm)
Public application (0.8KN; category C1-C4 and D): Toughened laminated 8/8/4 (17.52 mm) or 10/10/4 (21.52 mm) depending on the building height, wind load area, and balustrade height.
Public application (3.0KN; category C5): Toughened laminated 12/12/4 (25.52 mm) or 15/15/4 (31.52 mm) depending on the application, substrate, and balustrade height.
User Classes:
A: Spaces for living and domestic use
B: Office spaces
C1: Spaces equipped with tables (e.g., schools, cafés, reception areas)
C2: Spaces with fixed seating (e.g., theaters, meeting rooms)
C3: Spaces that do not obstruct the movement of people (e.g., exhibition halls, stations, hotels)
C4: Spaces where physical activities are possible (e.g., gymnasiums, stages)
C5: Spaces with large crowds (e.g., concert halls, sports halls, stands, platforms, etc.)
D: Shops
The price of a glass balustrade depends on several factors, such as the profile to be used, the type of glass, the anchoring, the scope of the project, and the complexity of the installation. The geographical location of the project can also play a role. As a rough estimate, the cost of glass balustrades will range between approximately 250 and 1250 euros per linear meter.
Absolutely! Glass balustrades are completely safe and can be used in most projects. There are systems suitable for residential situations and others that are more suitable for commercial environments such as shopping centers, stadiums, and office buildings.
To ensure the proper functioning of balustrades, each country has specific rules and standards in place. In France, the TransLevel balustrade systems are tested through:
* Experimental tests:
- By applying static loads
- By applying dynamic loads
- Or both
* Calculations
The exact delivery times and shipping options (parcel service or freight carrier) vary depending on the delivery destination, as well as the length, weight, and shape of the packaged order. Long items, such as TransLevel profiles, 5-meter handrails, or tubes, are exclusively shipped via a freight carrier. For smaller orders, we use a parcel delivery service like UPS. Shipping costs are calculated based on the specified delivery address.
