Other products

"The Zeleganz system uses non-fossil energy sources throughout, whilst at the same time allowing greater architectural freedom for the building envelope, both for new and existing constructions. It is encouraging to see how the adoption of an innovative, systemic approach enabled the development of a competitive range of products that also enables economic synergies. This is a great example of a successful technology transfer in the cleantech sector." Jury quote SIA Umsicht – Regards – Sguardi 2017, Switzerland
