varjuklaas

Varjuklaas, also known as tinted glass or solar control glass, is a type of glass that has been manufactured with a special coating or by adding specific compounds during the manufacturing process to reduce the amount of solar heat and light transmitted through it. This is achieved by either absorbing or reflecting a portion of the solar spectrum.

The primary purpose of varjuklaas is to improve a building's thermal performance and occupant comfort. By blocking a significant percentage of solar radiation, it helps to keep interiors cooler during hot weather, reducing the need for air conditioning and thus saving energy. In colder climates, while its primary function is solar heat gain reduction, some types of varjuklaas can also offer a degree of thermal insulation.

Varjuklaas can be manufactured in several ways. One common method involves a metallic or metallic oxide coating applied to the glass surface, often through a sputtering process. This coating is typically very thin but highly effective. Alternatively, coloring agents can be added to the glass melt itself, resulting in a body-tinted glass that absorbs solar energy throughout its thickness.

The appearance of varjuklaas can vary depending on the manufacturing process and the desired effect. It can range from subtle tints to more pronounced colors, and the reflectivity can also be adjusted. This allows for aesthetic considerations to be integrated with functional performance. Applications for varjuklaas are widespread, including residential windows, commercial buildings, automotive glass, and various architectural features where light control and heat reduction are desired.
