H.B. Fuller’s Ködispace 4SG Warm Edge Spacer System is the premier solution for both commercial and residential applications. Characterized by high energy efficiency, superior gas retention, and an automated process resulting in more precise spacer placement, Ködispace 4SG is currently the only reactive thermoplastic spacer system available.
The patented formulation chemically bonds to glass and silicone secondary sealant. There is no spacer migration, and it has a higher temperature stability than standard insulating glass with polyisobutylene (PIB) in addition to an increased resistance to incompatible glazing conditions. Its migration resistance is proven through extensive laboratory testing.
The invisible thermoplastic spacer system ultimately results in a more visually appealing insulating glass, creating a harmonious connection between glass and frame. Additionally, the auto-adjusting application provides unparalleled flexible design freedom and triple glazing manufacturing precision.
