Insulating Glass Market

Optimal energy-saving performance is driving the market growth

Market CAGR for insulating glass is driven by the rising number of energy-efficient materials in the construction sector. The high energy consumption in buildings propels the demand for energy-efficient building materials such as insulating glass. The utilization of insulating glass windows can help to decrease energy losses and result in lower energy consumption, which is a critical requirement. The heat and light transferred via the glass directly impact the comfort level of the people in the room, apart from affecting the energy costs. Switching to insulating glass windows greatly affects overall energy consumption.

The use of insulating glass in residential and commercial buildings can decrease power consumption by almost 50%, thereby proving to be an effective technology for power optimization. Also, the increasing trend of rating systems in various countries, such as LEED (Leadership in Energy & Environmental Design) in the US, IGBC Green Ratings in India, and others, are likely to contribute to the growth of the insulating glass market.

Leaks and drafts in windows result in heat loss during winter and cool air during summer, increasing electric bills. As per the Environmental Defense of Canada, the total greenhouse gas registered in Ontario consisted of almost 25% contribution from the equipment used for the buildings' cooling, heating, and lighting. This enhances the carbon footprint and contributes to climate change. However, growing awareness about environmental sustainability and solutions to decrease climate change has replaced existing windows. This, in turn, has boosted the requirement for the product, thus driving the insulating glass market revenue.

As per the prediction of the US Energy Information Administration, world energy utilization is expected to increase by 50%, with 2050-Asia being the primary consumer. This increase in energy demand leads to an expansion in commercial, industrial, and residential energy bills. Normal windows result in about 25-30% temperature loss, whereas insulating glass windows can save around 50% of this temperature loss. Therefore, an increase has been witnessed in installing these window, which restricts energy loss and contributes to reducing energy bills.

Strategic partnerships have emerged as a key insulating glass window market trend. Major companies operating in this sector are focused on partnerships and collaborations to strengthen their position. For instance, in October 2021, AGC Glass Europe, a Belgium-based insulated glass manufacturing company, and Masterframe Windows Limited, a UK-based window manufacturer, formed a strategic partnership to bring vacuum insulating glazing FINEO to the UK market for PVC-U sash windows.
