Flat Glass

Flat Glass
Flat glass is manufactured by allowing it to solidify on a layer of higher-density liquid, usually molten tin. This process is used to create clear, tinted and coated glass.

Flat glass is used for a variety of applications, including architectural and automotive glass. Precision measurements of temperature and uniformity of cooling are important for a high-quality end product.

AMETEK Land offers an extensive range of highly accurate instruments to provide the thermal measurements and data required for efficiency and product quality. We have supplied the glass industry with flat glass solutions for decades, developing dedicated solutions for specific applications within the process.
