Extra clear glass

WHY THIS GLASS?

From the underground area of the pavilion focusing on food of the future, the visitor takes a glass stair up to the central part of the Belgian pavilion: the light-filled geodesic dome. The staircase was designed to let in a maximum amount of light, but not alter colours. The obvious choice, both for the steps and for the banister that runs along the staircase, was extra-clear glass (Planibel Clearvision). The result is a pure, transparent design, with the curved banister following the rounded contours of the ensemble.

HOW DOES IT WORK?

Apart from raw materials like sand, soda and limestone, glass also contains oxides, such as iron, which generally gives it a greenish hue. This is especially noticeable if you look at the edge of a sheet of glass. The less iron it contains, the more transparent the glass will be.

Planibel Clearvision has a very low iron content, giving it a pure, neutral transparency.

How can extra-clear glass improve my daily life?

These days, the architecture of homes and commercial buildings is focused on bigger glazed surfaces. Taking greater advantage of natural light makes it possible to reduce the use of artificial light while enhancing wellbeing for occupants.
