A glass staircase, how is this possible? The glass is fragile, brittle. It's like Cinderella's famous glass slipper! A tale for children because how could one dance and run after the 12 strokes of midnight with a shoe in glass? So the glass staircase a staircase to fairy tale castle? What nenni!
The glass staircase
If it fits your home and your budget too, the glass staircase can become the most beautiful ornament of your home.
Glass a less fragile material than it seems
In fact, there is glass and glass. And as much difference between a simple glass plate and the steps of a glass staircase between the 2 horses Citroën Grand Papa and a modern car that parks alone!
There are several techniques to strengthen a sheet of glass and ensure your safety:
- Armored glass: This glass is poured with a wire mesh. In case of breakage, the latter retains the fragments of glass. Nevertheless, the risk of cutting remains high.
- Tempered glass: This is a glass which has been quenched, that is to say a heating of the glass plate followed by rapid cooling, which improves its mechanical resistance to shocks. But a toughened glass is not shatterproof. When it breaks, it splits into small pieces with little sharpness limiting the risk of injury.
- Laminated glass: It is an assembly composed of several sheets of glass (often quenched itself) between which are inserted plastic films (Poly-Vinyl-Butyral or Ethyl-Vinyl-Acetate) or a resin.
During a shock, the glass chips are held in place and will not cause injury.
The steps of a staircase are made with a laminated glass (glass trifeuilleté). While tempered or reinforced glass can be used perfectly for a railing or railing.
Advantages and disadvantages of a glass staircase
Innovative, transparent, luminous, light or at least giving an impression of lightness, the glass staircase gives a unique cachet to your interior. If it is done in the standards, it is totally secure.
It can be realized straight, rotating or helical.
Glass goes very well with wood, steel, stainless steel or aluminum. For example, you can choose a central steel or stainless steel stringer and glass steps.
It can also be stained, take color (colored film between layers of glass) or patterns, mingling or otherwise keep all its clarity (clear glass or extra-clear) to play with light.
But the transparency of a staircase all glass can be confusing especially young children or visually impaired people. Similarly, if you are prone to vertigo, such a staircase may seem uneconomic. Therefore, it is best to choose a translucent or frosted glass. The glass steps can also be inserted into a stainless steel rebate that will not make it heavier, make it look more "solid"
It is a staircase that must be frequently cleaned because the slightest trace of finger is seen...
The smooth surface of the glass can be slippery. Do not hesitate to ask for a anti-slip treatment or choose glass steps with a relief.
If it seems light because of its transparency, it is a finally heavy structure because the glass is anything but an ethereal material! A glass plate of 1 m² and 10 mm thickness still weighs 25 kg.
It is among the most expensive stairs. Depending on the shape, height and finish chosen, the price range is between 5,000 and 12,000 €.
Did you know? Laminated glass was invented by chance, in 1903, by Edouard Benedictus, artist and chemist! Perfecting his invention, he designed the laminated Triplex glass that gradually fitted the windshields of automobiles. It is the Triplex, which does not explode under an impact, which saved the life of Clémenceau during the attenta he was the victim in 1919. The Pyramid of the Louvre is the first large laminated glass building built in France.
