4SG Insulated Glass: Redefine Long‑Term High‑Performance Building Glazing
Traditional insulated glass with aluminum spacers faces common pain points: thermal bridging, argon gas leakage, edge condensation, and early fogging after years of service. That is where 4SG warm‑edge insulated glass (Ködispace 4SG system) stands out as a game‑changing glazing solution for modern construction. Built with integrated thermoplastic reactive spacer combining spacer, desiccant and primary sealant in one piece, 4SG forms chemical bonding with glass panes and secondary silicone sealant, creating a flexible, robust edge sealing system H.B. Fulle... . ✅ Outstanding sealing & long service life Annual gas leakage rate below 0.1%. Over 80% argon gas retention after 25 years, protecting Low‑E coating from oxidation and avoiding internal fogging. Passes strict EN1279 cyclic durability tests for long‑project‑cycle commercial and residential projects. ✅ Eliminate thermal bridging & stop edge condensation Metal‑free warm‑edge design largely cuts heat transfer along gl...
