Green building is now the norm, and we are committed to improving lives and protecting our planet. Through a wide selection of trusted solutions, we are helping manufacturers create long-lasting, energy-efficient and beautiful windows for any design or application. Whether we’re creating new sealant formulations, manufacturing products, or providing responsive customer support, we offer only the most advanced window glass sealant solutions.

We understand that the durability and reliability of a window relies heavily on the quality of insulating sealants and desiccants used in the manufacturing process. Because our customers require materials that can be used in a wide range of applications without sacrificing performance, we offer the premier industry-leading products for insulating glass sealants and desiccants, reactive thermoplastic spacers, window assembly adhesives, and glazing adhesives.

The addition of Kömmerling glass adhesives and sealants to H.B. Fuller’s portfolio not only strengthens our product line but also adds decades of experience and expertise to our team. Together, we can provide all of your insulating glass (IG) sealants from a single source.

Durable and Reliable Energy Efficient Solutions

Window Spacers 

Standard (Box), Composite and Foam Spacers - Our primary sealants and reactive and non-reactive secondary sealants are laboratory- and field-tested in a variety of extreme and accelerated aging conditions, ensuring reliability and application flexibility. We offer a solution for nearly every IG configuration: butyl-based, hotmelt, reactive hotmelt, polyisobutylene, polysulfide, polyurethane, silicone, and thermoplastic spacers.

Our Ködispace and Ködispace 4SG Warm Edge Spacer Systems with integrated desiccant are characterized by an extremely low moisture vapor transmission rate, good gas retention, high flexibility and long service life. 

The Intercept® Spacer System and GED lines were designed for speed, efficiency and quality, creating a perfect fit for our desiccant matrix, Insul-Cure® IG Sealant HL5153B and our broad line of hotmelt butyls.
