What is 21.52mm Low Iron Tempered Laminated Glass?
21.52mm Low Iron Tempered Laminated Glass is a high-end, ultra-clear safety glass specially designed for modern building overhead decoration.
It adopts high-purity low-iron glass as the base material, after strict tempering treatment, and is compounded with a standard 1.52 mm PVB interlayer to form the integrated 21.52mm overall thickness structure. Also named ultra clear skylight glass, low iron laminated roof glass, this 21.52mm Low Iron Tempered Laminated Glass features ultra-high light transmittance, no green tint, and a pure and transparent visual effect. It is widely used in building skylights, canopy roofs, high-rise curtain walls, and luxury outdoor decoration projects.

How is 21.52mm Low-Iron Tempered Laminated Glass Made?
21.52mm low‑iron Tempered Laminated Glass is produced by cutting, drilling, and edging low‑iron float glass first—its low‑iron composition eliminates green tint for ultra‑clear appearance—then tempering via high‑temperature heating and rapid cooling, placing a 1.52mm PVB/SGP interlayer between two 10mm low‑iron tempered panels, pre‑pressing to remove air, and hot‑pressing in an autoclave for permanent lamination.

FAQ
1. What is 21.52mm low-iron tempered laminated glass used for?
It is mainly used for building skylights, canopy roofs, terrace shelters, curtain walls, and high-end exterior decoration. It balances ultra-clear vision, high strength, and outdoor safety perfectly.
2. Is 21.52mm low-iron tempered laminated glass suitable for outdoor use?
Yes. It has excellent UV resistance, wind pressure resistance, and aging resistance. The 21.52mm thick structure is stable and safe for long-term outdoor skylight and canopy installation.
3. Does low-iron tempered laminated glass have a green tint?
No. Low-iron tempered laminated glass adopts ultra-clear low-iron base material, which greatly reduces green tint, presents a pure transparent effect, and has higher light transmittance than ordinary clear glass.
4. Is 21.52mm low-iron tempered laminated glass safe if broken?
Absolutely safe. As laminated safety glass, even if the glass breaks, the fragments will stick firmly to the PVB interlayer without falling off, which greatly reduces injury risk for overhead skylight and canopy use.
