The World of Glass Technology


Our main emphasis is on the maintenance, service and repair of insulating glass lines as well as providing spare and working parts. Doing so we have over 25 years of experience especially with machines and product lines from Lisec.

When buying and selling used machines, we overhaul them for further use in our own plant in order to guarantee our customers optimal functionality. A great variety of spare parts is stored in our extensive high-bay warehouse so we can react quickly to your problems.

We carry out our work worldwide at the customer’s site or in our spacious workshop. Extensive employee training for operating and maintenance personnel completes our service.

We are happy to inform you about our prices and GTC and we are available for any questions you may have about insulating glass lines.

Udo Werner founded the company
Isolierglasmaschinen Service Udo Werner
in January 2001. His mission: A competent service maintains customer’s productivity.


The team and warehouse were constantly growing and required a switch to a more suitable company form in 2006. Since then we have been operating under the name
IS Werner GmbH & Co. KG.


With our 3 competent technicians and an extensive spare parts warehouse we are now able to carry out even larger projects quickly, reliably and at the same time.



For our customers it is crucial to rely on our ability to solve complex problems. This only works with a skilled team.


Only operating machines make profits. Therefore high reaction speed, quick installation and maintenance of insulating glass lines are essential for the productivity of our customers.


Our extensive warehouse including the most common spare and working parts means we are able to repair damages within short notice and protect customers from shortfall in production.
