The Next Generation of Spacers
The Ködispace 4SG thermoplastic warm edge system from H.B. Fuller | KÖMMERLING has been awarded the ASC Innovation Award by the North American Adhesive and Sealant Council (ASC). With the next-generation spacer, the world’s largest supplier of adhesives and sealants for insulating glass applications has been impressing the US construction industry since 2016.
In early November 2020, the Adhesive and Sealant Council based in Alexandria, Virginia (USA), presented its coveted Innovation Award for the fourth time. The ASC Innovation Award is aimed at promoting innovation in the adhesives and sealants industry, as well as in the scientific community. An independent jury evaluates the solutions submitted for their innovative strength and the impact of the technology on the state of the art. H.B. Fuller | KÖMMERLING impressed the jurors with its Ködispace 4SG thermoplastic spacer and was honoured with second place.
The Adhesive and Sealant Council (ASC) is a North American association representing the adhesives and sealants industry. It is an alliance of over 100 adhesive and sealant manufacturers, suppliers, distributors and industry consultants. The ASC offers its members a platform for knowledge exchange, promotes collaboration for innovative product development and represents the industry as a common interest group.
Ködispace 4SG wins over the jury
Ködispace 4SG is a reactive thermoplastic spacer for use with insulating glass. As a next-generation warm edge system, Ködispace 4SG combines spacer, desiccant and primary sealant in one product. Since Ködispace 4SG chemically bonds to both the glass surface and a silicone secondary sealant, the entire edge seal “melts” into a highly durable unit. This results in permanently tight and extremely durable insulating sealed units. Another significant advantage is the flexibility of Ködispace 4SG: It absorbs deformations without creating significant stresses in the edge seal. This makes the warm edge system especially suitable for the most demanding of mechanical applications, such as the cold bending of insulating glass units, where it offers a clear advantage over conventional, rigid spacers. Ködispace 4SG is ideal for the production of insulating glass for standard windows, as well as more complex structural glazing applications.
“We are very pleased that the Adhesive and Sealant Council has acknowledged Ködispace 4SG’s potential and rewarded the value of the solution,” said Dr. Christian Scherer, Head of Business Development Glass at H.B. Fuller | KÖMMERLING. “With our spacer system, we not only ensure energy-efficient, durable insulating glass, we also offer planners and building owners virtually unlimited design freedom, thereby enabling innovative glass designs. To date, more than 15 million square metres of Ködispace 4SG insulating glass units have been installed worldwide, achieving long-term energy efficiency in thousands of residential and commercial buildings – from small single-family homes to huge skyscrapers with stunning architecture – and therefore providing a valuable contribution to the fight against climate change.”
In the flowing glass roof of the Chadstone Mall in Melbourne, Australia, the flexible warm edge system with Ködispace 4SG ensures permanent gas tightness for the cold-bent insulating glass panes.

Due to its special composition, Ködispace 4SG forms a chemical bond with the glass as well as with the secondary silicone sealant. The insulating glass therefore becomes a firmly bonded yet flexible unit.
