What makes ISOLAR^® glass stand out is the brand’s continual level of high quality. This level is guaranteed by an extensive, three-stage system of quality management: Every manufacturer does his own factory production control(production steps and finished units) daily.

Beyond this, the manufacturer’s production and internal controls are carefully monitored by ISOLAR^® group employees and by employees from the "Institut für Fenstertechnik" (Institute for Window Technology) in Rosenheim.

Insulating glass products are considered "regular construction products" according to the planning regulations and building laws in the Federal Republic of Germany. In order for the insulating glass products to be used by the clients, they require the so-called "U-Marking". ISOLAR^®'s quality control and the supervision provided by the Institut für Fenstertechnik assure that ISOLAR^® glass fulfils these requirements.

These demanding quality standards are at the same time also a solid starting point for tomorrow’s needs. They are the ISOLAR^® group’s head start when it comes to including new "official" characteristic values to all ISOLAR^® glass products. And they are our head start for future or upcoming European norms. Short: Our head start is your advantage. In this regard, the brand ISOLAR^® also guarantees quality and safety.
