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.
