Flat glass manufacturers operate large-scale industrial facilities where silica sand or recycled glass cullet is melted in high-temperature furnaces and drawn or floated into continuous sheets of flat glass. Finished product may include standard clear glass, tinted glass, coated glass, or laminated safety glass used in construction, automotive, and industrial applications. Operations typically run continuously, with significant utility consumption, heavy material handling, and specialized finishing or cutting lines.
Questions to investigate
- What is the total insured value of furnaces, float lines, and processing equipment, and how current are those valuations?
- Is the facility a continuous-process operation, and what is the estimated furnace rebuild timeline in the event of a major loss?
- What silica dust exposure controls are in place — engineering controls, respiratory protection programs, and air monitoring?
- What are the primary end markets for finished glass — construction, automotive, specialty industrial — and what is the distribution channel?
