H.B. Fuller’s Ködispace 4SG Warm Edge System is the premier solution for both commercial and residential applications. Characterized by high energy efficiency, superior gas retention, and automated processes resulting in more precise spacer placement, Ködispace 4SG is the first reactive thermoplastic spacer system available.

H.B. Fuller Ködispace 4SG, initially developed for structural glazing façades, is now widely used in insulating glass for both residential and commercial applications. Its unique material properties create highly durable and energy-efficient insulating glass units (IGUs). Unlike conventional thermoplastic spacers, Ködispace 4SG’s chemically bonds to both the glass and silicone edge seal, ensuring long-lasting energy efficiency and durability.
