ENERsign

What does the term forend mean?

Execution of a double-wing window. After opening both wings, a continuous opening is created. Double-wing windows with mullions, on the other hand, have a vertical division in the frame after opening of both wings.

Windows with mullion convince in the open state with even more free space – here the window elements are not separated by a web. One of the two sashes can be turned and tilted with one handle, as with the transom, the other can only be turned and thus opened by means of a hand lever, but not tilted. Forend variants are only possible with double sash windows. Advantages with forend: large open area when open.

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.
