Advances In Manufacturing For Sustainable And Energy-Efficient Glass
As buildings become smarter and sustainability-driven, manufacturing plays a much deeper role than simply shaping glass. Today’s production technologies influence energy savings, resource use, end-of-life recycling and environmental responsibility. With climate concerns rising and architects seeking low-energy structures, manufacturers are under pressure to deliver glass that performs better and lasts longer – without harming the planet.
Advances in manufacturing are driving greener and more energy-efficient buildings. Precision coating technologies now enable glass with better insulation properties, reducing heat gain while maximising natural light and lowering energy requirements for cooling and lighting. Manufacturing processes are also becoming more resource-efficient, with reduced water usage, cullet recycling, lower carbon emissions, and a stronger focus on end-of-life recyclability. These improvements are steadily steering the industry towards sustainable construction, explains Bansal.
Adding to this, Choudhari states that sustainable manufacturing of safety glass has progressed noticeably through recycling of raw materials, electric and hybrid furnaces, waste-heat recovery, and AI-enabled automation. High-performance coatings, insulated glass units (IGUs), chemical strengthening, smart glass integration, and circular economy practices are helping reduce defects, waste, and long-term environmental impact.
Major Challenges In Developing New Façade Glass Products
The demand for high-performance façades is rising, but so are expectations. Architects want glass that is lighter yet stronger, safer yet more transparent, and energy-efficient without becoming unaffordable. This makes product development an intricate process, where engineering, quality, regulation, climate and installation challenges must align perfectly before a new glass product reaches the market.
Striking a balance between performance, cost, and scalability remains the biggest challenge. Although technologies such as dynamic glass and multi-functional coatings are available, high pricing can limit adoption in price-sensitive markets like India. Climate adaptability, larger and thinner panels, logistics, installation complexities, and awareness among stakeholders further add to the difficulty of developing new façade-specific products, notes Bansal.
For safety glass used in façades, these challenges become even more demanding. According to Choudhari, fire-rated glass requires advanced interlayers, coating technology, whole-system testing, and third-party certification. Bullet-resistant glass struggles with weight, thickness, warping during lamination, size limitations, and high cost. Ensuring optical clarity, blast-resistance, energy-efficiency, proper installation, and compatibility with framing systems requires extremely precise engineering.
Size And Global Positioning Of India’s Glass Industry And The Façade & Fenestration Segment
India’s cities are growing at an unprecedented pace, and with them, the demand for modern glass buildings. As premium real estate, commercial hubs, and green-certified structures increase, the glass sector plays a critical role in shaping skylines. But how does India compare with global markets, and how fast is the façade segment evolving within the country?
India’s glass industry is valued at over ₹35,000 crore, with the façade and fenestration segment accounting for nearly 20–25% of total demand. Rising urbanisation, premium real estate growth, and green building certifications are major contributors. Compared with global markets such as the U.S., China, and Europe, India remains emerging but stands out as one of the fastest-growing, states Bansal.
Supporting this, Choudhari shares that in 2025, the Indian glass manufacturing market is valued at approximately $12.7 billion, with façade and fenestration alone contributing around $1.5 billion. Although India’s share remains smaller than that of advanced Western markets, strong construction activity and modern architectural adoption continue to push the country into a competitive global position.
