Whether it’s light tints, frosted finishes, or vintage styles, tinted glass can be customized to complement the aesthetic preferences of any building’s doors and windows.
Low-E Glass
Low-E (Low-emissivity) glass, often abbreviated as low-e glass, features a specialized thin layer of metal or metallic oxide coating applied to its surface during manufacturing. This coating enhances the glass’s ability to insulate against heat transfer by minimizing the transmission of infrared and ultraviolet (UV) rays while still allowing visible light to pass through. During summer months, Low-E glass reflects a significant portion of the sun’s heat away from the building, keeping interiors cool and reducing reliance on air conditioning. Conversely, in winter, it reflects heat back into the building, preventing it from escaping through the glass. This dual functionality ensures a more consistent indoor temperature year-round, improving comfort levels and reducing energy consumption. Additionally, Low-E glass effectively blocks UV rays, safeguarding interior furnishings, artwork, and flooring from fading and sun damage.
When selecting Low-E glass, it’s essential to consider two main types: passive Low-E coatings (hard coatings) and solar control Low-E coatings (soft coatings). Solar control Low-E glass is often recommended for residents in the United States, particularly in warmer climates, as it provides superior solar heat control compared to hard coatings. However, hard coatings may be more suitable for colder climates or regions with milder summers where retaining solar heat is desirable. Despite representing an initial investment, the long-term benefits of Low-E glass include reduced energy costs by minimizing the need for heating and cooling systems. Given that approximately 90% of window and door heat loss occurs through glass, the use of Low-E glass can result in significant energy savings over time. Overall, Low-E glass stands as an effective solution for improving energy efficiency, maintaining indoor comfort, and enhancing sustainability in both residential and commercial buildings.
