A Low-E Glass with High Transparency and Thermal Insulation

SunGuard® High Performance Neutral 55 is a low-emissive glass that offers high transparency with thermal insulation to suit challenging projects. With visible light transmission of 53%, this glass can help meet the demand for greater use of natural light in current architecture. SunGuard® High Performance Neutral 55 combines transparency, low reflection, and solar heat gain in one product. It also has a neutral appearance that help enhance the aesthetics of many buildings.

SunGuard® High Performance Neutral 55 can be used in various applications, such as facades, roofs, skylights, windows, and spandrels. It is especially recommended for laminated applications, where it can provide additional benefits of safety, security, and acoustic performance. SunGuard® High Performance Neutral 55 requires edge deletion and must be laminated or used in insulated glass units (IGU), and it can be tempered in both compositions.

If you are looking for a high-performance glass that offers great transparency and solar control, SunGuard® High Performance Neutral 55 is a good choice for your project.
