# Low-Emissivity Glass Panels Pilkington Optitherm Glass Reduces Outside Heat Transfer By Colin Smith | Published 2024-02-05 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/optitherm References: [pilkington](https://www.pilkington.com/en/global/knowledge-base/types-of-glass/energy-efficient-glass/low-emissivity-glass) Low-emissivity (low-e) glass is a type of energy-efficient glass that prevents heat from escaping through windows to the cold outdoors. Pilkington Optitherm is a low-e glass product that has an invisible coating that reflects interior heat back into the room and reduces heat transfer to the outside. Pilkington Optitherm also allows most of the sun's energy to pass through the coating, which means it can provide natural light and warmth to the indoor space. Pilkington Optitherm has a very low thermal conductivity and can help save energy and reduce heating costs. Pilkington Optitherm has significant implications for the glass industry, as it represents a high-performance and cost-effective solution for thermal insulation. Pilkington Optitherm can improve the Window Energy Ratings of existing window frames by up to 75%, which can increase the demand and value of low-e glass products in the market. Pilkington Optitherm can also benefit the environment and society by reducing the carbon footprint and greenhouse gas emissions of buildings that use low-e glass. Pilkington Optitherm can be used for various applications, such as residential buildings, commercial buildings, conservatories, and sun rooms, where thermal comfort and energy efficiency are important factors.
