  • What is hidden behind the word absorption?
    In the field of windows, absorption is found in thermal insulation and soundproofing windows, where they reflect heat back into the room if possible or absorb sound waves so that less noise can penetrate into the rooms.
  • What counts as acquisition costs?
    The sum of all expenses that must be incurred in the case of a property purchase. As a rule, these are made up of - Purchase price of the real estate - costs for a contract mediation, brokerage fee, costs for the conclusion of the contract (notary / court fees, land register fees). Furthermore, any taxes that may be incurred (land transfer tax) as well as acquisition-related expenses. These acquisition costs may be tax deductible in the form of a deduction for wear and tear (Afa).
  • Why is airtightness so important?
    The passage of air through joints and cracks in the building envelope has many disadvantages. For example, a high percentage of all structural damage is caused by leaking building envelopes. The sound insulation is reduced, draughts cause discomfort for the residents and unnecessarily high heat losses are incurred. For this reason, the applicable standards have for many years required that the outer shells of buildings must be airtight.
  • What turns windows into airtight windows?
    The air tightness of a window depends decisively on the number of sealing levels. In order for windows and doors to be airtight, the airtightness tapes must also be cleanly applied on the building site. For buildings with increased requirements, it is recommended that an airtightness concept be drawn up during the implementation planning phase. The a-value is used to measure the air tightness, which is used especially for testing windows and doors (DIN EN 12207).
  • What's an alarm spider?
    Alarm spiders are electrical conductor loops that are placed in the corner of the inner surface of the glass. If the pane is smashed during an attempted break-in, the glass shatters into many small fragments. The power supply is interrupted by the glass breakage, so that the alarm is triggered by the cut conductor loops. Triggered by the breakage, the burglary protection of the window, the so-called glass breakage alarm is used and an alarm is triggered.

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.
