Insulating Glass Window Market Overview and Definition

The global insulating glass window market size was valued at USD 12.5 billion in 2021 and is projected to reach USD 24.3 billion by 2032, registering a CAGR of 6.5% during the forecast period 2022-2032. Windows have been the weakest energy efficiency link in the building atmospheres. Insulating glass is an evolution from older technologies such as double-hung windows and storm windows which used a single pane of glass to separate the interior and exterior spaces.

Insulated glass refers to two or more lines of glass sealed around the edges with an air space between to form a single unit. A window with insulating glass is known as a double glazing or a double-paned window, triple glazing or a triple-paned window, or others, depending upon how many panes of glass are used. These insulated glass windows and are spaced apart and hermetically sealed, leaving an insulating air space.

Glass is an ideal material for packaging of products, as it reduces the risk of contamination and protects products from damage .Glass insulation improves thermal performance by providing a thermal break between the glasses Also, some variants of glazed insulated glass provides several benefits such as superior insulation, UV protection, reduced outside noise, enhanced security and acoustics among others.

The insulating glass window market is expected to witness growth at a steady CAGR over the years to come.

Insulating Glass Window Market Drivers

The growth of this market is attributed towards major relying factors such as the rapid expansion in the building & construction sector in emerging countries, the improving optimal energy saving performance of insulating glass windows, the rising demand for value added glass products globally, rising awareness about energy efficient buildings, increasing demand for non-hazardous, green, and sustainable adhesives for glass window, increasing number of legislations and regulatory guidelines for more efficient forms of energy conservation, growth in investments in research & development activities by major players in the market etc.

Additionally, the standard followed today is that of a double-glazed low-E window with insulation between the panes. Depending on the region of the country, windows have a U-factor of 0.30 to 0.60 and a solar heat gain coefficient of 0.27 to 0.40. Insulated glass windows primarily lower the U-factor, but also efficiently lower the SHGC accordingly.

Moreover, the heat transfer by convection, radiation and conduction are decreased by the extra window and air void present in an insulated glass. Insulated glass can be further fabricated to meet sound control requirements, seismic requirements, bullet resistance, hurricane and blast resistance requirements, impact resistance, and state energy codes. This, in turn, propels the market for insulating glass windows.

Furthermore, commercial constructions that use insulating glass windows include commercial buildings, offices, hotels, hospitals, educational institutes, stadiums, and airports are increasing their usage. Consequently, the increasing demand for Green Buildings in the commercial construction segment has been observed globally.

However, high cost of raw materials and glass bonding adhesives than conventional ones, lack of awareness along with low adoption of this type of glass in many underdeveloped countries, emission of harmful gases such as CO2 in the glass manufacturing process while melting raw materials and universal directives pertaining to applications of insulated glass are factors that hamper the growth of this market.

Also, the ongoing pandemic is estimated to have a huge impact on various factors of the value chain of insulating glass windows, which is impacting the overall market negatively.
