  • What is a blind?
    Nowadays, a blind is understood to be a variable visual and sun protection. The external blind (not to be confused with the roller shutter) serves like the internal blind for privacy and light protection but protects more effectively against heating in summer. The slats of the blind are made of roll-formed aluminium, wood or - especially with inexpensive models - PVC. The most common slat widths are 16 mm, 25 mm, 35 mm and 50 mm. Venetian blinds are available with perforated slats, colours, patterns, sizes, shapes. Even triangular or trapezoidal systems are possible within a certain range.
  • How does the BlowerDoor test work?
    The BlowerDoor test, also known as the differential pressure method, can be used to reliably measure the air tightness of buildings. The measurement is carried out after the windows have been installed and the air tightness level has been completed. By means of a ventilator inserted into an opening in the outer shell (front door or window), an over- or underpressure of 50 Pascal is generated. The air exchange rate is calculated on the basis of the amount of air that is blown in or sucked out. If the air exchange rate is too high, any leaks must be found and repaired. The maximum permissible n50 value (= air exchange rate) is 0.6 h-1 .
  • Why do you need brackets and angles?
    If the window is located in the insulation zone of multi-layered wall systems, supporting structures, e.g. brackets etc., are necessary. The fixing itself must be dimensioned in such a way that the expected wind and payloads are absorbed and the dead weight can be carried at right angles to the window plane even when the sash is open.
  • What does the term building envelope mean?
    In energy-saving houses, the entire building envelope is excellently insulated. The building envelope consists of all components that separate the interior from the exterior. The interior should have a comfortable climate - the weather determines the exterior.
  • What happens during the building inspection?
    The building inspection is the acceptance for use or final acceptance after completion of the shell by the approval authority. It is checked whether all legal requirements for building permission have been fulfilled and whether the building has been constructed according to the plan. In addition, building inspection also refers to the final acceptance of the building or individual trades by the building owner.

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.
