IGK Insulating Glass Sealants

Quality – Service – Innovation

IGK supplies the basic adhesives and sealants needed to produce insulating glass windows: primary and secondary sealants and the Thermoplastic Spacer®.

The quality of our products has contributed to making us the European market leader of insulating glass sealants made from polyurethane.

As an SME (small and medium enterprise), we know each of our customers personally. And each of them knows: IGK understands my business and has a service, on which I can count at all times.

Developing innovations is how we define ourselves and what spurs us on. We launched mercury-free polyurethane on the market back in 2001 – many years before the announced ban on mercury.

Our headquarters are in the heart of Germany and you can find our branches and representatives all over Europe and overseas.
