A transparent thermal coating ultra high performance: the Crystal GlassX

GLASSXcrystal integrates 4 system elements in a single functional unit: Transparent thermal insulation - protection against excessive heat - energy transformation - thermal collector.

A triple insulating glass structure offers excellent thermal insulation with a U value of less than 0,48 U = W / m2K.

A prismatic glass placed in the space between the panes reflects the summer sun outwards when it is at its highest, with angles of incidence greater than 40 °. On the other hand, the winter sun crosses the sun protection at its full intensity.

The central element of GLASSXcrystal is a thermal accumulator module which absorbs solar energy and releases it with a time lag in pleasant radiant heat. A phase change material (PCM) in the form of a salt hydrate is used as an accumulator. The accumulation of heat is effected by the melting of the PCM; for cooling, the accumulated heat is released again. The salt hydrate is hermetically sealed in polycarbonate containers.

Inside the premises, the element is closed by a 6 mm single-pane safety glass, the arrangement of which can be changed.
