Tempered Glass Side Panel

Tempered glass side panels became the standard case windowing material from approximately 2017 onward, replacing inferior acrylic (perspex) windows. Tempered glass is 4–5× stronger than standard float glass due to surface compression from rapid cooling during manufacture. It is safety-rated (shatters into small blunt fragments rather than sharp shards), optically distortion-free, and scratch-resistant. Panel thickness is typically 3–4 mm. Tinted, smoked, and clear variants are available. Full-side and partial-side tempered glass panels are offered on virtually all mid-range and premium cases from every major manufacturer.
