Top 5 Companies in the Global Flat Glass Market in 2025

The global flat glass market reached a value of about USD 134.45 billion in 2024. The market is projected to grow at a CAGR of 6.5% in the forecast period of 2025-2034 to reach around USD 252.38 billion by 2034.

Flat glass, or sheet glass, is produced in a flat or planar shape by floating molten glass on metal sheets, allowing for flexibility and recyclability. This versatile glass type finds application in windows, glass doors, furniture, tabletops, transparent walls, windshields, solar cells, and windscreens, showcasing its diverse utility in various products. Unlike container glass, flat glass can be bent, adding to its functionality in different industries.

The global flat glass market is projected to witness a significant share dominated by the construction sector, among various end-use segments, throughout the forecast period. The sector's substantial contribution is attributed to escalated infrastructure activities, fuelled by rapid urbanisation and the initiation of smart city projects, thereby fostering both segmental and overall market growth.

Amid a heightened emphasis on the visual appeal of residential and commercial spaces, there is a burgeoning demand for decorative glasses incorporating digital print technology. Consumers exhibit a willingness to invest more in products that offer superior quality and visual allure. The pliability and favourable attributes of flat glass make it a preferred choice for crafting these decorative glasses, contributing significantly to the flat glass market growth.

In September 2022, AGC, a global leader in glass, chemicals, and high-tech materials, disclosed through its subsidiary, AGC Glass Europe S.A., that it aimed to produce a float glass range with a notably diminished carbon footprint.
