  What Is Tempered Glass? Tempered glass, also called toughened glass, is a type of safety glass processed by controlled thermal treatment to increase its strength compared with ordinary (annealed) glass. When broken, it shatters into small, granular chunks rather than sharp, jagged shards—reducing the risk of serious injury. It is approximately 4 to 5 times stronger than annealed glass of the same thickness and is widely required by building codes for applications where human impact or thermal stress is a concern. How Is Tempered Glass Made? The tempering process involves three stages: Cutting and edge processing — The glass is cut to size, and edges are polished or seamed. Any drilling or notching must be completed before tempering, as tempered glass cannot be cut afterward. Heating — The glass is fed into a tempering furnace and heated to approximately 620°C (1,148°F) , near its softening point. Quenching — High-pressure air jets rapidly cool the glass surfaces.

  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...
