About KÖMMERLING

Founded in Germany in 1897, KÖMMERLING Chemical Group is now part of H.B. Fuller, a global leader in adhesives. Its Ködispace 4SG won the Adhesive and Sealant Council (ASC) Innovation Award in 2020 and is a new-generation, integrated, flexible warm-edge insulating-glass sealing system.

What 4SG Brings to Your Windows 

Traditional insulating glass relies on the physical assembly of "aluminum spacers + butyl sealant." 4SG adds chemical adhesion on top of physical bonding—reacting polysulfide or silicone sealants into a reactive sealant that completely replaces conventional spacers, molecular sieves, and butyl.  Long-lasting argon sealing — A shift from physical to chemical bonding delivers seamless, durable argon retention.  Warm-edge energy efficiency — Metal-free construction provides lasting airtightness and stable thermal insulation, eliminating thermal bridges at the source.  25-year warranty — Insulating-glass service life extended beyond 25 years, with a 25-year warranty against argon leakage.
