High light transmission (approximately 87–90%)
Excellent optical clarity
Perfectly flat and smooth surfaces
Uniform thickness
High chemical and weather resistance
Fully recyclable
Typical physical characteristics:
Density: ~2,500 kg/m³
Low thermal expansion
Good mechanical strength for further processing
Float glass is a high‑quality flat glass produced by floating molten glass on a bath of molten tin. Because molten glass has a lower density than tin, it spreads evenly across the surface, forming a perfectly flat, smooth sheet with uniform thickness. This process produces glass with excellent optical clarity and minimal distortion.
Today, float glass is the base material for most architectural, automotive, and industrial glass products worldwide.

Float glass is available in a wide range of thicknesses, including:
2–3 mm: Electronics, interior applications
4–6 mm: Windows, doors, furniture
8–10 mm: Facades, shopfronts
12–19–25 mm: Structural and industrial applications
Thickness tolerances and quality requirements are defined by international standards such as ASTM and ISO.
