An elegant light gray glass that helps create comfortable interiors filled with natural daylight

Guardian SunGuard Solar Light Gray 52 is a solar control glass that has a subtle gray hue, creating a contemporary and elegant look. It allows a high level of light to enter the space, while reducing glare and solar heat gain, helping to provide thermal comfort and energy efficiency. It also preserves the natural colors of the outside view, so you can enjoy the scenery without distortion. This glass is perfect for projects that require a lot of natural light and a cozy and inviting ambiance.
