Correctly renovate windows, refurbishment - costs, instructionsRenovation of windows on the north side of a building is - according to experts - of particular importance. Heating costs can be saved especially in this area on a large scale.
However, it may very well have fatal consequences for a building that generally has poor insulation anyway to renovate the windows alone.
After all, it has been proven that the air in the rooms settles on the (inner) walls over the course of time, forming condensation and resulting in mold fungus.
The most diverse renovations taken together, so for example, the renovation of the roof, the facade and the windows makes sense in any case. A much more harmonious "interaction" of the climatic conditions (influences from inside and outside) is therefore possible within the building as a result.
In principle, the financial expenses for window renovation amount to between 150 and 450 euros per square meter. However, these are only current, statistical guidelines. However, this "flat rate" sum depends on a variety of different factors.
In this context, for example, the desired sound insulation play a role, as well as the fact whether perhaps even a double or triple glazing is desired. Furthermore, the aforementioned cost aspect has an effect on the shape, size and material properties of the new windows in each case.
Not to be forgotten in this regard, of course, the heat permeability,
the profiles of the window frames et cetera. Even the desired design of the windows is decisive here.
Flexibility is needed
Against the background of cost savings, it might even be advisable not to plan a complete window replacement, but instead to think about a glass replacement. The costs
In comparison, this amounts to just eighty to Euro per disc - depending on the quality, of course.
The frames, if they still meet the current quality standards, will simply continue to be used. The environment is happy and also the household budget is relieved in this way. Nevertheless, energy costs can also be saved by such cost-saving renovation measures.
Nonetheless, the aspect of economy should never be overlooked. For example, the purchase costs for new windows in the amount of around 5,500 to 7,000 euros (for a single-family dwelling with a 110 m² floor area and a window area of about 25 m²) should be considered.
In fact no "cardboard handle". In contrast, however, there is an expected energy saving of as much as 4,500 kW / h. To what extent this financial expenditure proves to be worthwhile, can be determined among other things very easily on the Internet, with the help of special on-line computers.
As part of such a price comparison, both the possible price increases of the energy provider, the annual oil consumption, or the kW / h price are calculated.
Individual numbers can of course also be introduced and taken into account during this online calculation. By the way: even the heating costs incurred over a certain period of time in connection with the total costs for the windows in particular are taken into account in the course of the online comparison calculations.
Of course, such factors can also be clarified during a consultation with public (funding) agencies. In any case, this is a time effort that turns out to be well worthwhile and profitable. Both with the help of the Internet and on a personal level, future-oriented plans can be explicitly and competently clarified.
