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 systemH.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 glass edges. Warmer interior glass edges greatly reduce condensation risk, delivering stable U‑value performance decade after decade.
✅ Clean modern aesthetics
Sleek matte black edge, no butyl overflow. Delivers nearly border‑less visual effect for curtain walls, high‑rise facades, sunrooms and glass partitions, perfectly matching minimalist architectural styles.

✅ Wide application scope
Ideal for hidden‑frame curtain walls, passive houses, zero‑energy buildings, swimming‑pool enclosures, skylights, triple glazing and oversized insulating glass units for demanding climate conditions.

For projects chasing reliable energy‑saving performance, long‑term durability and premium visual results, 4SG insulated glass is your smart glazing choice.

Glass Market Outlook: Supply-Demand Reversal Marks Bottom Rebound in August

Image
 he domestic glass market is poised to exit its bottom range in August, driven by a notable supply-demand reversal . Delayed downstream demand has officially been released, alongside active restocking from primary glass manufacturers, setting a solid foundation for a market rebound in the peak seasonal consumption period. As of late July, downstream deep-processing enterprises maintained order backlogs of 9.4 days, a marginal year-on-year decline of merely 0.1 day, reflecting resilient fundamental demand. The second half of the year traditionally ushers in a seasonal destocking cycle, with average daily demand expected to rise 5%-15% month-on-month versus H1, landing at a conservative 2.5-2.7 million weight cases (compared with 2.81 million weight cases in the same period last year). Fundamental data confirms a clear tightening trend in supply and demand: H1 Oversupply Phase : The average daily melting volume stood at 146,500 tons, with a daily oversupply of 5,400 tons.

Glass Market Poised for Bottom Recovery in August Amid Striking Supply-Demand Reversal

Image
 After prolonged inventory buildup and muted fundamental performance, China’s flat glass market has finally hit a turning point in August, marking a decisive reversal of the industry’s long-sluggish supply-demand balance. A confluence of rebounding downstream demand, proactive production curtailments and elevated fuel costs has pulled glass prices out of their bottom range and kicked off a sustained destocking cycle, setting the stage for a gradual uptrend throughout the third quarter. Improving downstream demand serves as the primary catalyst for the industry’s turnaround. As of late July, glass deep-processing firms held order backlogs of 9.4 days, edging down only 0.1 day year-on-year, which reflects solid and stable operational activity downstream rather than weakening demand. More notably, construction-related glass demand deferred in earlier months has started to materialize in a concentrated manner. Downstream processors, which have long maintained lean inventory levels, hav...
