Outstanding Quality

Since decades, Gartner is known as a leading curtain wall manufacturer. The company  developed many of the international standards in force today. This experience and the in-house quality requirements characterize Gartner façades and services.


Gartner assumes the contractual warranty for all products supplied and installed after formal acceptance by the client. The necessary service and maintenance is described in the user information.

Service & Maintenance

Gartner also offers the service and maintenance of façades. As manufacturers we are acquainted with the object-specific uniqueness of our façades and their complexity. We are therefore able to detect damages, operating errors or eventual other defects at an early stage and take the necessary measures to avoid secondary damages and warranty problems. We are also available to arrange for service that exceeds the statutory warranty periods or take over such services for projects from other manufacturers of suppliers.
