Thermal stress from uneven solar heating can shatter glass curtain walls. Precision edge processing—using polishing, double-edging, CNC, beveling, and washing machines—eliminates micro-cracks that trigger breakage. Recognize failures by clean, right‑angled cracks with arc‑shaped central lines. Prevention requires proper design, installation gaps, and heat‑treated glass.

Organic glass (acrylic/PMMA) is a plastic, not real glass. It offers high transparency, strength, light weight, and easy processing – unlike ordinary glass that needs heavy machines (double edger, washer, beveler, groover). It is widely used in transport, architecture, medical, and defence applications.
