What do you need sun protection for?

Sun protection (also known as shading) in architecture aims to protect buildings and their users from the unwanted effects of strong solar radiation. These unwanted side effects consist of glare and reflections as well as overheating of the building. Another important function is protection against UV radiation, for example to prevent furniture from fading. Despite the sun protection, a high degree of transparency should often be maintained. Due to the extensive use of glass in modern architecture, sun protection also plays an important role in façade design. Depending on their position and function, a distinction is made between different sun protection systems, which have different advantages. External sun protection, such as the awning, the external venetian blind, the roller shutter, the armour, the window shutter, the folding blind or the curtain, function primarily via absorption. The internal sun protection is realized, as for example with the venetian blind, by the principle of reflection.

Welcome to the ENERsign® U-Value window configurator:

The U-value window is also called heat transfer coefficient and according to the standard DIN EN 10077 it indicates the amount of thermal energy lost through a window to the outside.

The U-value window is calculated using the formula W/(m²K), i.e. watts per square metre and Kelvin. This value refers to the entire window and defines the amount of energy per unit of time that flows through an area of one square meter when the air temperature on both sides differs by one Kelvin. The lower this value is, the less energy or heat the window emits.
