Glass Thickness, Glass Type and Glass Processing


Go Back

Tomislav Bacic, manager of the Sliding Systems department with over 20 years of experience at Glas Marte, frequently answers questions about planning, installation and maintenance. Today he is talking about glass thickness, type and processing.

When do you use what glass thickness?

This depends on the system and the installation situation: What is the height and width of the system, how much weight does the sliding system have to withstand? For this reason Glas Marte offers different systems. Our recommendations are given in the planning manual. Our in-house and field service advisors are happy to answer any questions.


What glass should you use for high wind loads?

That also depends on the system. Generally we use TSG. On 3rd/4th floors of buildings however that is less recommended because TSG needs to be thicker here and in the event of glass breakage, that means larger pieces of falling glass. It's better to use LSG/TSG or LSG/HSG here. The thickness depends on the glass thickness dimensioning. This in turn depends on the installation and system height, the glass width and the wind load.


How do you choose the grading of the individual glazing types?

Our sliding systems can slide in both directions. It's up to the customer whether the system slides left to right or right to left. The customer can also choose the number of elements. Glas Marte naturally advises as to whether the elements might be too heavy. We recommend an element ratio of 1:3. If a system is 2,500 mm wide, the width of a sliding element should be at least 800 mm.

We recommend an element ratio of 1:3.

Do you recommend nanocoating on the glass?

Not really on sliding systems. Nanocoating is designed for showers which are frequently in contact with water and are wiped daily with a shower wiper.


How do you prevent birds from flying into the glass?

Glas Marte offers a range of bird protection options.


Is any glass processing necessary?

The system technology means that glass processing is required for all GM TOPROLL® systems. Holes must be drilled into the glass for the additional retaining device. In terms of the system technology GM LIGHTROLL® systems do not require processing apart from edge polishing. However, if a shell handle is wanted, holes must be drilled for this.


Why is the running rail not colour-coated?

The lower running systems are supplied as standard in EV1. This finish offers good surface protection. If you coated the runners, the finish would wear off in time due to the roller action. Nevertheless, if a customer has a special design requirement, we shall of course apply a coating, albeit with a reference to the risk of wear.
