GLASSX crystal integrates 4 system components in a functional unit: transparent heat insulation, protection from overheating, energy conversion and thermal storage.

It combines the characteristics of PCM (Phase-Change-Materials) with self-regulating solar control in highly insulating, energy saving double-glazing. PCM produces clean solar energy to heat the room to a comfortable level exactly between 26 °C and 28 °C. GLASSX crystal uniformly radiates the stored energy in a controlled way into the room. At the same time it lightens the room with a good dose of diffuse daylight.

The various size options of GLASSX crystal enables a flexible use. The individual designed interior surface allows to fit the element in different scenes.
