The global flat glass industry is expected to reach an estimated $66.6 billion by 2019.

Growth is expected to be driven by demand from the automotive and construction industries.

The growing demand for energy efficient glasses has encouraged OEMs to switch to insulated glazing from single glazing units, and as such players such as NSG and Asahi Glass have introduced solar control glazing and lightweight glazing.

This is projected to give new shape to the glass market in the next decade, and despite various challenges, the market for flat glass is expected to grow over the next five years.

Lucintel, a global management consulting and market research firm, has analysed the global flat glass industry by segments and region, and has come up with comprehensive research report "Global Flat Glass Industry 2014-2019: Trend, Forecast, and Opportunity Analysis."

On the basis of its research, Lucintel forecasts that the majority of the segments for flat glass industry will grow moderately in 2014-2019.

It states that architectural trend such as glass in patio doors, extra natural lighting in building and large windows will result in additional demand for flat glass in building construction.

The biggest challenge in the industry is determined as the rising cost of raw material and energy. Sluggish demands in developed countries and requirement of efficient logistic management are also pinpointed as challenges to the growth of the industry.

Flat glass manufacturers will be required to make innovations in their manufacturing process in order to meet the changing needs and standards of the industry.
