GLASSX®store is a passive cooling element for curtain-wall constructions. It contains a translucent PCM layer, on both sides protected by toughened safety glass. The GLASSX®store elements extend from floor to ceiling and are mounted a few inches behind the actual façade.


During the day the PCM absorbs both solar radiation and internal heat load. Leveraging this thermal capacity, the conventional HVAC system can be significantly reduced in size or even be eliminated altogether.

Since GLASSX®store is mounted in the interior the architect maintains full freedom in design and choice of material for the glass façade.


Thus, GLASSX®store is perfectly suitable for combination with any curtain wall design ranging from the award winning tower to the retrofit of overheated office buildings from the 1970s.
